Humans by nature are sentimental… and we cling to too much, we have to have too many material things, I don’t know if that’s mostly being American or not….. there’s nothing wrong with your point of view ……your memories of your father and mother are the best things that you could have….. thank you for sharing your collection….. and it’s quite obvious you’re not cold about your father as if that were the case he wouldn’t of felt like sharing with your friends…..I’m sure he’d be proud for all of the right reasons
