The Bike Gets Rusty. Don't you know?

They say if you learn to ride a bike once, you will always know how to. No matter how long you don't ride it. But after sometime the bike gets rusty.

This is the metaphor I would use for this particular situation I want to talk about. But timing issues related to exams preventing me from developing this description of the situation. So this entry is just a reminded for myself to develop it further after the son of the fucking bitch that are exams.
