I mean, I'm sure we can come up with a lot of reasons why not to do it.
My point was just that you don't need to choose between hanging out with your friends and making a new friend. You never know, that person could become a friend for life. I think it's worth making the effort but I understand it's not for everyone.
I'm selective about who I keep as friends but I try not to close myself off initially, as I've been on the other end of it as well; being in a new city and trying to make friends. With some people it just doesn't click, while others I still have as some of my best friends.
Anyways, I wasn't trying to upset anyone, just giving my 2 cents
It’s a lot to ask someone to drop into a group of 4+ friends of 10+ years and just hit the ground running. It takes a lot of effort from everyone involved. I’m for it but it’s not as simple as one might assume.
