She told stories , flirted outrageously with boys and was constantly changing her hairstyle . Anne Frank hid with her family in a secret room at her father Otto Frank 's office in Amsterdam . It could be the description of almost any young girl growing up in Europe . But this is how Eva Schloss remembers her childhood friend Anne Frank , who had she not died in a Nazi concentration camp , would have celebrated her 80th birthday this week . Schloss described Frank , whose account of hiding from Jewish persecution in Nazi-occupied Amsterdam is one of the world 's mostly widely-read books , as a spunky young schoolgirl with a passion for storytelling that often got her into trouble . `` She got her diary in 1942 , so obviously her father knew she was interested in writing and I know she told stories , '' said Schloss . `` She talked a lot and she was called Mrs Quack Quack . Very often she used to write hundreds of lines [ at school ] of ' I 'm not going to talk so much , ' and so on -- but obviously she had a lot to tell . '' In some ways the two friends lived parallel lives -- but tragically they had very different outcomes . Watch more about Schloss ' story » . Schloss and Frank both came from Jewish families who fled to Holland to escape the wave of anti-Semitism spreading across Europe as the Nazis rose to power in Germany ahead of the Second World War . But while Schloss was more of an introvert , Frank loved the limelight . Schloss said : `` I was actually quite shy and she was the center of attention . We had steps where we sat , and she had a crowd of children around her . `` She was a big flirt -- she loved boys . She was always showing us who was her boyfriend at that particular time . She was always interested in her clothes . Her style , she always changed it . Sometimes she had curls , then she had straight hair . '' Schloss says they were unaware of the full scale of what was going on around them as war escalated across Europe , placing their lives in increasing jeopardy . `` Our parents really protected us so there was no talk about the horrendous things which happened . `` You could n't go out anymore after 8 o'clock , but for a 11 to 12 year old it did n't matter so much . Or not going to the cinema -- we were upset about those little things which we could n't do , but we really did n't really take it seriously at that time . '' Like Frank , Schloss was also forced into hiding when the Nazis took control of Holland . Frank hid with her family in a secret room at her father Otto Frank 's office . But Schloss and her family had to split up . Schloss stayed with her mother while her father and brother hid elsewhere . She and her mother moved around , staying in seven different hiding places over a two-year period . Eventually both families were betrayed and were sent to concentration camps , where Frank died at the age of 15 . Schloss said : `` My father and brother were betrayed by a Dutch nurse who was a double agent , and all four of us were arrested and taken to the headquarters to be interrogated . `` I did n't know anything , which was a good thing . So eventually they realized this and they gave up torturing me . Within two days we were put on a transport to Auschwitz . '' Of her family , only Schloss and her mother survived Auschwitz , one of the most notorious concentration camps , located in southern Poland . Today Schloss , who has just celebrated her own 80th birthday , has a husband , three daughters and five grandchildren . Schloss says it took her decades to rebuild her life , with the help of Frank 's father Otto , who also survived incarceration in a concentration camp . She met Otto in August 1945 , when he showed her Frank 's diary . Schloss said : `` He read a few passages but he always burst into tears . It took me 20 years . I was really unhappy , but it was Otto who came to our apartment to talk to us , and he helped me a lot . He had lost everybody . `` Her book , she [ Frank ] made people aware of what happened . There are many messages . She believed in the goodness of mankind . `` People always ask me , what she would have done . I guess we will never know . But I guess she would have gone into politics -- she was a fighter . It 's a pity , but also -- maybe her diary would have never been published . '' CNN 's Don Riddell contributed to this story .
