127. Ask friends to refrain from updates on the last time they saw your ex

If you haven't see a friend in awhile and one of the first things she brings up is, "oh so I've been seeing so-and-so every single time I go out and..." stop it right there. No one wants to hear about how their ex boyfriend is blacked out every time he makes an appearance in the Marina. Save yourself the unnecessary embarrassment and make it clear you have zero interest in anything he's up to.
