Do you remember your first time?  The first time you tried the new math; a whole different way to do something you had already being doing properly for years.  The first time you saw a Twitter fight, or a comments section. It reminds you that a lot of people just plain suck.  The first time someone decides to write a check that now you have to pay up on.  They are all memorable first times, but that first time using a bidet may just top them all.
