What I think

If you’re walking slower than the guy pushing the mop, you don’t need to occupy a treadmill.
If you have no clue what you’re ordering, you don’t need to get in the 3 person line yet.
If you’re not sharing with everyone in your minivan, you don’t need a 64 oz mug of soda.
If you’re going a total distance of two blocks, you don’t need to drive.
If you’re only reason is that you love your voice, you don’t need to raise your hand in class

and
if you have nothing new to tell me, you don’t need to call my office.

Questions on that?
