Concuss Straight on Bus

wah 2day i on bus totally concuss straight after i sat down. too tired to open my eyes to keep myself awake. during the journey, a lot of ppl were boarding the bus and walking towards the back. i was sitting in the middle of the bus. then cos i was in a slp state, my body couldnt support my posture. so i tend to sway towards the 'corridor' of the bus. then a lot of ppl walking pass ma, then i opened my eyes n went back to my original position. :\ furthermore, the most interesting thing is dat, when the bus was coming to a stop in a bus-stop, it turned direction and i swayed all the way left! (almost fell out of my seat man!) luckily i woke up in time n used my footing to stop me frm falling off the seat. then i look back to the guy sitting to my right and smiled to him. :D then i went back to slp again, lol... embarrassed sia... the whole bus was filled wif ppl... :\
