Quiet down myself for what?

Morning student in school.

Afternoon guitarist in service.

Evening pig in the bed. Ermm.. not going to sleep, just want to blank my mind for a while... after hearing so much noise.... it is time for me to quiet down. There is time that I need to be alone and quiet down myself, but sometimes people just cannot understand why we (not everyone) want to be alone. This is a way for us (not everyone) to recharge our physical energy.
