Wendy has a system when it comes to changing our towels:  After [x] number of days, put old towels in wash and bring out new towels.  That [x] is pretty small; somewhere around 7-10.  My system is a little different:  After [y] amount of smell develops, put old towels in wash and bring out new towels.  The problem with my system is that [y] is usually much greater than [x] (actually they can't really be compared unless smell can be quantified as an integer; but you get the idea).  Sometimes [y] reaches an overwhelming value in 7 days.  Sometimes it's more like 18.  I'm thankful I have a good sense of smell that prevents me from allowing [y] to get too large.  As soon as I notice a smell on my towel, it's over.  More than likely, it means it's been about 2 months since I started using the towel, and judging from the towel's heartbeat and limb growth, it's time to use a clean one. 

The cool thing about clean towel day is that it always makes me happy.  What can I say; I'm simple.  For an unexplainable reason, it gives me a small but noticeable amount of pleasure.  It's like getting your hair cut or getting your car washed.  Clean = happy.  I wonder if this idea isn't universal.  Maybe some people equate dirtiness with happiness?  Perhaps.  But for me, I like clean things.  And since today was clean towel day, it's a good day. #psychology
