after changes upon changes we are more or less the same

Every morning when we're driving into Shawn's work, we pass a store with a large billboard that says, "Coat and Glove Sale". For some reason, almost every morning, my eyes reverse a couple of letters so I read, "Goat and Clove Sale". My mind actually pictures it... goats and cloves... and rejects it. The whole process of glancing at the sign, picturing that weird mental image, and rejecting it as wrong and then correcting myself, it all only takes a split second. I just find it strange that my mind does the whole thing over and over and over again, even though I've seen that sign every morning for weeks on end.
