I'll start first.
This happened about a week ago. I was taking the #8 back home from NAIT, and it stopped at the mall. A few people got on and an older looking guy sat beside me who was wearing a blue jean jacket and blue jeans (I was in the back section). Well, I though he was normal until he started rocking back and forth in his seat the whole ride and yelling out random words. When the bus stopped for people he would start to yell "no. NO!" and start slapping his hand and his knees. If it was a longer stop he would announce that we had been there for "a minute...we've been here a MINUTE!!". Everyone on the bus was looking at this guy, I think he had some sort of mental illness or something. Thankfully he got off the bus down town which is one of the earlier stops, as I was sitting right next to him.
Oh, and today I got off the #8 to transfer to the #4 and when the #4 finally gets there after 20 minute of waiting, the operator said the bus was "not good". So I end up waiting for a new bus to arrive...
