My little sibling has typically been entirely shy.
Even though that is the case, he has typically been serious and doesn’t care about playing around! He loves reading about things and studying everything he could. He has been fascinated with books as well! One time, I bought him some DIY heating and air conditioning service books for his birthday thinking that he might want to learn something about that. He entirely loves those books that I got for him and it entirely got him interested in studying more about HVAC repairs and maintenance. Before I knew it, he was typically changing the air filters to the heating and air conditioning unit in our house while we were growing up, it was a chore that he was never assigned although he insisted it was necessary so that we could have good air quality in our home. I wasn’t surprised when he ended up getting his HVAC certification plus then he started entirely working for a reputable HVAC corporation. He still is a little bit shy to this day and he doesn’t say much, although he entirely is a wonderful HVAC serviceman. He has a wonderful deal of pride in his work plus I don’t think anybody could ever complain about him messing up with an heating and air conditioning system repair! Probably one of the only things that he doesn’t care about about his work is when he has to train people. He doesn’t like talking much, although he does good because he is able to teach people by showing them what to do. Occasionally I tell him he should begin his own HVAC corporation, and with a drastic look, he says that will never happen.
