What most
people reading this is suffering from ''Boredom"
This infection is easy to but
hard to cure. This infection can be caused by simply a teacher teaching something you already know or by your lack of tv show recorded or by simply binge watching Bobs Burgers.
The only cure is by doing something mildly interesting like counting the nails on a
wall or by playing around with siri (Or cortana if you have an Microsoft phone)
But sadly there is no medical cure so instead of being bored on your ass all day
go for a job and be productive.
