While shopping for straws, I noticed that the store sold only Jumbo and Giant sized straws.  Since I didn’t know the difference between “jumbo” and “giant”, I compared them.  As near as I can tell, “jumbo” seem to be a normal sized straw while “giant” seemed to be a little longer.  But, since they didn’t offer small, medium or large, I bought the “jumbo”.  Life is too short to worry about straw sizes.
