T5 reasons Being without your own shopping bags is comparable to being without pants

 I'm to the point where using my own cloth shopping bags seems just as normal and right as wearing pants.

1.  When you're just starting out, you probably forget to bring your own shopping bags/wear pants.
2.  The more you see the importance of bringing your own shopping bag/wearing pants, the more you notice when others don't.
3.  There are benefits to bringing your own shopping bags/wearing pants to the store.  (You don't have to pay for your plastic bags/get credit for bags you aren't using...and they will let you in the door, etc).
4.  You feel naked when you are at the store without your own shopping bags/pants.
5.  At the end of a long day, sometimes you just don't care about bringing your own shopping bag/wearing pants, and that's ok too. Sometimes.
