Pros and Cons of envelopes

Pros:

• It "envelops" things.
• You don't have to use it for mail, you can put apple slices in it, for example.
• They come in different sizes.

Cons:

• Apple slices don't keep too well in them.
• They do not do a good enough job of telling you where to lick to close the envelope.
• Can't ever remember how to put them in the printer so the address is printed right-side up.
