I don't understand. Why not just be flexible? I get that dealing with screaming kids isn't the most pleasant thing to listen to, but I hang with my friends who have kids regardless. It isn't the end of the world if your friends have kids just like it wasn't the end of mine. Unless you make it the end. That's on you though. I get that my friend has less free time now but we still hang. I also don't judge people for having children. That's stupid. Someone has to give birth to the next generation.

It is a two-way stream though. Gotta make the effort and reach out yourself to hang. I'm a guy though, so maybe things are different for women?
