Ticks. (the little bugs that burrow into your skin) Adults who insist on going onto buses first so they can slow school students down. Adults who go onto buses and force school students out of their seats. I'm happy to stand for someone who actually needs a seat but sometimes it gets ridiculous. Being on the verge of a great gaming achievement only to have my computer lag and screw me up. (specifically talking about super meat boy) My maths teacher insisting that i take my textbook to school everyday when i could put it on my laptop, puts my bag past 8kg and kills my back if i miss my second bus on fridays.
