person A: My little brother was stuck gaming on a horrendously slow computer for years.
person B: That's not much fun. Did he get a new one recently?
person A: Kind of. I built myself a new PC_comma_ and gave him my previous one. I re-built it for him and made sure everything would work perfectly!
person B: Wow_comma_ you're smart and kind! I wouldn't know where to start re. building a computer. Well done!
person A: Thanks! Seeing him smile as he played with high frame rates and nice graphics brought me such joy. 
person B: What a nice thing to do. You seem to get on very well with your little bro.
person A: I love my siblings so much_comma_ they're the best.
person B: I love my brother_comma_ too. He's a great guy. How lucky we are!
