It might seem weird, but I really don't like going to the toilet at school. There are various reasons for my schooltoilet-phobe.
Firstly, I think it is just so awkward how other people can hear you pee. Or even worse, when you're stereopeeing together with a random stranger. This is one of the reasons why I always try to go to the toilet during the lessons, since then there is the smallest chance of meeting someone.
Even worse is when you are done and there is no toiletpaper. At home you can just scream for help, but school = school, which means screaming for toiletpaper is not the done thing. Instead, you have to text all of your friends for help and hope someone will come and rescue you.
Secondly, one of the taps on the ground floor is broken. I never remember which one it is, but for one reason or another it seems to always be the one I use. This broken tap means water spatting everywhere. On the mirror, on the floor and unfortunately, if you have opened the tap completely, it even spats on you, making it look like you have just used the shower instead of the toilet.
During the breaks, (another reason why I prefer using the toilet during the lesson) there are always girls fixing their make-up in front of the mirrors. Apart from the fact that I don't get why they do that - I am really too embarassed to do that while there are other people present. The faces I make whilst putting on make up are the worst - I really hate it, since they block the access to the mirror and they never go away when they see you have to use the sink, till you politely ask them, to which they reply with rolling eyes and you're just like, wow I am sorry for using the sink for what it was actually build for.
Furthermore, the fact that some girls find it necesarry to take pictures in the toilet?? While you are washing your hands????
I mean it is so weird. Why would you take a selfie with your friends in the school toilet? There are so many places in school to take nice pictures, and mirror selfies really are the worst. It is like you just saw yourself in the mirror and thought, wow I am so pretty right now, I should celebrate and show everyone by making a picture.
Washing your hands while standing next to such a photoshoot is one of the most awkward things. You never know where to look and you just hope they haven't heard you pee. Moreover, there is a leave-us-alone-and-don't-judge-us-cause-we're-cool-atmosphere, which makes you feel very unwelcome.
Solution
It is hard to hold everything till your home, so that's why I think going during the lessons is the only solution and to just accept the fact that this may affect your grades in a negative way (you miss the important material discussed during your stay at the toilet).
