Is it an oil change or is it something else?

Today has been a rough day but also bright in lots of ways too, this morning I had to get my car looked at which turned out to be a continuing sago that will last through Monday ugh.  As I'm sitting in the waiting room I strike up a conversation with this older man from Clearwater, found out he as in town for his son's basketball game and had to get his car looked at as well.  So since we were in the same boat we decided to pass the time by talking to each other.

As I look back on the conversation I can't help but wonder why it happened, I wonder if there was something more spiritually significant going on?  If there was I wonder if I made the test did I do what God wanted me to do, the conversation did go into what I did for a living and what I'm studying to become?  My prayer this day is for him and his family that maybe a seed was planted and that I have more oil changes like this on.
