Social Rules and Suit Coats

There are rules involved with certain social situations, not always noticed and not always followed. I committed a faux pas over the weekend and fortunate enough for me, a loving brother thought to bring it to my attention so that I'm prepared for the next occasion. And in the spirit of sharing, I think these rules are good for any suit-wearing man to remember.. So, you're welcome.

Some context; I attended a Baptism of a family/friend's child on Saturday and sent some pics to the family email in an update.. I later got this response and it made me lol:

(My family is AWESOME!)
