Little Kids at the Bus

Everyday I am being bothered after the very first hour of the day. I hate how the little kids keep on bothering me at the bus. Especially because they sit some of them in front of my seat. They are always screaming at each other like if they were talking to a depth grampa.they don't stop hitting the back of the seat with their backs like if it were falling on top of them. They also start arguing that they want to seat alone and fight to seat alone. Some of them even turn back and watch you until you ask them to stop searing at them.
The worst part of all is at the 3:00 bus I always come tired from studying and try to sleep but no matter how or what I do they wont let me. I don't know how they still have energy to waist after all that time studying normal persons get tired. And if you get to sleep and sleep with your mouth open they will start to get close and giggle until you wake up. They will throw you papers and everything they have. The worst part of all is when they vomit; they will vomit and they dint care where they vomit they don't care if its on your things they should at least ask the bus driver to stop the bus so that they can vomit. That's why I will always hate how they behave at the bus ride.
