My work has thought me to always check everything and be careful, so I'm trying to avoid traps.

It's difficult with the older generation. I'm really sorry to know your dad is not listening to you. The worst thing is when they think they are the smartest and they know everything. It wasn't easy for me with my dad either, but now he knows he needs to listen and after he has seen how others have been fooled, scammed, he's careful.
