Cumbersome

You know about fat kids that are troublesome. Like bullies. So, cumbersome means troublesome and really hard to handle.Here are a few sentences:
1. Mostly they tend to be slow and cumbersome, and this is made worse when you're running inside a small virtualised OS.
2. That workaround is just not acceptable, its slow, cumbersome, and fools people when things change.
3. It was heavy and cumbersome, and she realized, in her unskilled hand, useless.
Ok, those were a few sentences. Today I need to go early to school because I'm going to The Academy of Sciences. I have to be at my school by 8:00. So, bye!
