Mad Max

Early in our relationship, my college boyfriend Jason compared his affection for me to the last can of gasoline in a Mad Max-like world. If you had the last can of gas in the world, you wouldn't go around *talking* about it, would you? 

Part of the conversation went something like this:

Me:  But you do have a can of gas?
Jason:  I can't talk about it.  For obvious reasons. 

This conversation was typical of our exchanges, and for most of college, we got along quite well.  I'm not sure, though, whatever happened to the last can of gas in the world.
