Girls Who Go to the Bathroom at the Same Time

I enter the girls’ bathroom and there’s a huge pack of girls standing by the sink, doing their makeup, so when I’m don,e they’re in the way. It’s really awkward asking them to scoot over because I’m not friends with any of them. So what do I do? If I leave, they’ll spread rumors about me for not washing my hands. If I ask them to move, they’ll probably yell at me, and if I push them out of the way they’ll scream and smear eyeliner all over their ugly faces. You choose. But why do they all go to the bathroom at the same time? I really don’t understand.
