You have them, they have them, and sometimes you have the same ones, but the matter of the fact is they are there.
Now we know that it’s only two people in an actual relationship, but face the fact, you will see your friends and your partners friends every once in awhile. Make sure you be yourself, don’t be quiet, try to find common ground with at least one of them. Tell your friends to be themselves too, even if your friend is a pain in the ass and cracks jokes about everything… your date may like that.
Just make sure they don’t fall for your friends more than you.
If your friends have something bad to say about the person you’re dating, let it slide, unless you’ve been dating for a long time then tell them to shove off. It’s your relationship not theirs.
