My kid brother is getting married in a few weeks (he's back in one piece from gis Vegas bucks' night).
I feel that being the eldest sibling here I should take him out for lunch and convey some sort of wisdom to guide him or at least let him know I want this to work and I'll be there for him no matter what.
Any suggestions as to what I should say or what you wished your loved ones had told you before the big day?
He knows about the birds and the bees in case anyone decides to be smart.
