Why do women go to the washroom in groups?

Well im a woman but im not necessary like the ones you described, though when i was younger i used to prefer to go to the washroom with a classmate of mine. When i was young the reason being that i wanted to be with someone i need to go is because of the ghost stories that seem to circulate around every comfort room in every school that i know, so that was my reason no 1. I was afraid of ghost which is silly... yeah i know... Then when i was older like in highschool- the reason was because the CR doors in the school that i was in was broken so i needed someone to hold it for my while i do my business, then id do the same to her when im done- seriously, that was really my reason until the door was fixed. Then come college- this was the time i prefer to go to the CR alone, so from then on i went when i want to alone... no ghost can scare me now.. For others, i think its because when they would like to talk about a certain topic that they cant talk about when they are with men, like when they would like to give their immediate feedbacks about their dates! or some quick girl talk...the washroom seems to be a perfect place for conversations such as that, and it gives them privacy too.

I guess we do it to make sure we fix our hair/makeup right. I think some might do it so they have someone to talk to to drown out the sound of farts...

There are two reasons 1. They are scared to go alone 2. They can discuss lots of secrets in the Wash room.

I always wonder why women use to do this and I have no response.
