It is alright to sleep on the MRT. 100% fine. It just isn't all that fine when a man asleep KEPT 'accidentally' tilt his head and lie on your shoulder. It is not fine when a man asleep KEPT dropping his itchy hand from his bag and then 'ACCIDENTALLY' touches your butt - AGAIN.and AGAIN like it is for FREE. The worse thing that could happen at this point of time is that you can't get up also since the train is so freaking packed.
Thankfully the uncle sitting beside me noticed this pervert. He shifted one seat for me. Once I moved, another girl sat down. And there goes the sleepy man's 'accidents' again.
