Top five pet peeves

1.  When people touch my laptop screen (or any other laptop/computer screen) when pointing to something. Does my laptop have a touchscreen? No, then why are you touching it like it's going to open some link or perform some command. Stop.  
2. When people enter or leave a room and do not shut a previously shut door. To quote Panic! at the disco "haven't you people ever heard of closing the damn door" 
3. When people go around saying they have OCD when they really don't. OCD is a mental illness that affects a persons ability to carry out their daily tasks and thus affects their quality of life. It's an actual problem. One that you don't have just because you like things to be placed in a certain way. I'm not opposed to people saying they have Obsessive Castle Disorder (OCD) or Obsessive Christmas Disorder (OCD). 
4. Actually when people claim they have any mental disorder when they don't. Please stop. 
5. When my sister uses my towel. *groans* We share a bathroom and my room is right by the staircase making it easier to access the bathroom from my room when coming from downstairs. Also my sister has her towel hanging outside her room so she always exits using my room so she can use the towel. I can deal with using my towel to wipe your wet hands but she messes it up and lets it fall sometimes too and that grinds my gears.
