this one is a sarcastic recommendation. you probably shouldn’t do this. all i’ll have to show my grandchildren someday are photos of me with my face contorted into various unattractive expressions. i’ll say “well… this is just who i was at the time…” and they’ll have nothing to post on their instagram stories when it’s Grandmother’s Day.
my Genuine recommendation is this: smile for photos. do it for your grandkids.
