Paper or Plaster

Every time I go grocery shopping, it’s the same damn question:
“Paper or plastic?”
Plastic’s good for putting the scooped-out clumps of kitty litter into.
But the kitties like to play in the paper bags.
In the end, I settled on paper. The baskets on my bike are large enough for one paper bag each.
The one time I got plastic, I couldn’t fit all the bags into the baskets.
With one bag dangling from my right hand, I fell and broke my left arm.
I use a plastic bag to keep the cast dry in the shower.
