what are the chances?

Last night my husband and I were invited to Susan and Scott's (new friends of ours) home for dinner. She and her husband have a son in recovery who was friends with my son (T) at one time. They have a beautiful century home and garden.  We had a delicious dinner served outside with a beautifully decorated table.  Everything - all the details were noted by me and I felt she even put Martha Steward to shame.  The other guests that attended were an adolescent drug counselor (who helped me tremendously a few years back) and a married couple, both juvenile probation officers.  The male tried to help me get T into drug court way back then and I remember how helpful he was - going out of his way to meet me at the school to try and talk to T.  It was embarrassing, though, because all T did was hear a portion of what he was trying to explain about the program, then stood up , gave him the finger and said "F - You".  I figured he heard it all before, but it was still uncomfortable, not too mention - frustrating.  After dinner and a chat by the fire on their side lot, they all left , but my husband and I stayed a little bit longer, and then Susan told us that this PO, I just mentioned, started the juvenile drug court in our area - that is very successful.  Since then other places have used his model.  
Well, just about when we were ready to leave - my friend, Susan, said that someone left a bike on their next door lot the previous night and so they turned it into the police. I then joked and wondered if it were mine because T takes it sometimes and I don't see it for days. Well, I knew it wasn't mine because mine was at home.  T also takes J's bike and the same thing happens - it's missing for days.  We're always trying to track it down - sometimes driving to pick them up.  
Well - she told us that the bike was green.  I just knew it was J's!  We then started to a describe the other details and ..... lo and behold - it was the bike!  They live about a 20 minute walk from our home - so it isn't like we live nearby.  The bike was left by the fire pit in their lot next door.  I wonder if T was with her son or was it a coincidence that T just decided to leave his bike there?  Her son looked so clean-cut - it's hard to imagine our son hanging out with him.  Anyway - as I know there is no such thing as a coincidence - it's still hard to believe.  Right after the visit - we went to the police station to pick it up and yes - it was the bike.  Going out to buy more bike locks.  Sad we have to do that.  T's birthday is coming up.  He might be expecting a new cell - I want to buy him a bike.
