I need help with meaning: 「それは気の毒に...年頃だしな」


それは気【き】の毒【どく】に...年頃【としごろ】だしな

How would you read this sentence?

"It is unfortunate...that age" ? It doesn't make sense to me

Edit: The context is a bit tricky because it seems to me like the old man who
says it about the hormonal teenager is a pervert




年頃 basically means someone is in the transition between child and adult. Being
curious about something romantic, or disobedient etc. I don't know which
English word corresponds to it, but I think its like

"It's understandable for his age".
