Mine is from my grandparents. Their advice was to save some of the "weird sex stuff", so that way if I forget a birthday or anniversary I have a last minute gift idea tucked away....*shudders*. They like to make shit awkward for me, that's for sure. Another weird one was from FH's aunt and uncle who we don't get along with. Their advice to us was to travel the world before starting a family. Great advice, if we didn't already have an almost 4 year old, who we are actually really excited about traveling with.
What's been your favorite weird/odd advice?
