Why do girls always go to the bathroom together even when one of them doesn't have to go?

Its a get a way. We go in there to talk about guys, grades, school, work, anything. Most likely we follow the one who have a problem and we're gonna go try and see if we can help. But I really don't think we notice that we do that. Most of the time when a group of 4 or 5 girls go into the bathroom, only 1 or 2 have to go. I don't know why exactly we do it, its just something we do.

It bugs me too! And I'm a girl! Haha well mostly some girls just don't want to go alone. It may be safer. Or they want to talk about something or someone. Or they don't want to be talked about. Or someone needs some feminine products! Haha can't forget that one. Yeah its annoying I know.

Gossip and safety in numbers

We do this to talk about things we don't want the guys to hear. Either it's a "Wow I like him so much!" or " What a douche bag!" But yeah that's why lol

Like the other gals have said, it's sort of a combo thing. We don't want to leave someone standing outside by them self just kind of waiting for us to get back. Going to the bathroom is a chance not only to use the facilities, but also to fix hair, check makeup, etc. , to make sure we still look hot.

And yeah, I'll admit it, the bathroom is a private space where we can gossip about guys. Especially at a club or something, cause it's relatively quiet in there and the guys can't hear us. It's the place to say, "Can you believe that creep? Everyone just let me know if you see him again so I can clear out," or "OH MY GOD did you see that hottie at the end of the bar? Carrie, I'm gonna need a wing girl when we get back out there. " Stuff like that. ;)

Well personally I only go with someone if I'm just out with 1 of my girl friends don't want to leave her there like a loner and its a chance to fix make up etc. But if there is like 3 or more of us out we just go in on are own

Yea I'm a girl and if I were a guy id think it was weird too. Usually, it's because they wanna make sure they look good. Hair, makeup, clothes. Or they just go to talk to their friend about something that is happening(like a problem if they don't wanna talk about it in front of the guy)

We don't want to be alone lol one goes we all go and its a good excuse to keep looking in the mirror making sure we still look hot for you guys

It's a bit of a private space that they can go to chat. You're not there, so they can talk about you but not to you. There's that reason, as well as the secret cult they all join at birth that makes them try to confuse guys endlessly. Be careful, though - it's a dangerous secret.
Seriously though - it's just so they can socialize without a male's presence.

I think it's because they are raised that way. They also like to gossip.

The better question is:

Why do girls that go to the bathroom together take pictures of each other on the toilet!?

I mean could you imagine two guys like talking it up in the mens bathroom and like taking pictures of each other at the urinal.? That would be really really really. REALLY WEIRD

Ever been in the ladies room? Hell some of them have carpet and nice furniture, The damn bathroom is a nicer place to be than at the table your sitting at.

I learned the answer to this one long ago. It is a social event for girls. Don't be bugged by it. You're not ever going to change it!
