a person riding a bike slows down and comes to a stop at a bike lockup post, he gets off his bike and locks it to the post. as he leaves he stops and turns and looks back at the bike to make certain it is locked to the post something he does each time he locks up the bike now since he lost a bike the year before by not having the lock around the post and the bike frame. as he does this two are females walking by him and one says to the other "and now he takes two steps and turns and looks over his shoulder". and they both giggle strangely.
a couple of weeks after that incident he left his bike locked to a bike post in the same area and when he returned and unlocked the bike and began to ride south on yonge street he heard a clattering sound from the rear fender. he stopped and took a look back at the wheel and could see a piece of wire about the thickness chicken fencing is made from it is stuck in the tire. he gets off the bike checks the tire from which he can hear the air hissing from and removes the wire, the tire goes flat. so he pushes the bike to a bike store where they change the inner tube.
a couple of months later he returns home one night and parks and locks his bike in the space inside the hallway used for that and goes down stairs to his room which is below the hall area where the bike is locked up. one of the other tenants who lived upstairs liked to leave the front door open all night "to get a breeze he said", that night a few hours after locking up his bike he was laying in bed reading and thought he heard someone up in the hallway moving his or one of the other bikes, he was going to get up to go and check and then the sound stopped, and he laid back to continue reading, that was when he heard through the rooms open window a sniggering giggling sound coming from the general area of the public sidewalk at the front of the house.
when he went upstairs to unlock his bike in the morning he got as far as the front step before he
understood the back tire on the bike was flat while the tires on the other bikes in the hall were ok. so
he pushed it back to the bike store and they changed the innertube and the tire which had been slashed. a couple of weeks after after that incident he began to notice people stopping in front of him on the sidewalk a little ahead of the back tire of a bike locked to a post and then turn to look at the back tire of the bike.
