For guys anyway, it seems like Your friends are like dogs. No matter what, they’re happy to see you. Scratch behind their ears and they’ll follow you anywhere.
In the same way, Her friends are like cats. They could care less if you’re there or not there. If you don’t feed them they’ll take off and find another home to live in.
The “Our Friends” you had as a couple are like pidgeons. Startle them and they all fly away.
Be your own best friend. At least you’ll know where to find him, even if he isn’t always the best company.
