[Sundae]

You can never have too many wax earplugs.

You will lose half-full boxes.
Your cat will chew the ones you left in reach because 5 years is not enough to teach you that lesson.
The one time you are absolutely, completely, nowhere-else-to-look out of earplugs, your parents will have a horrible row that you really did not need to hear as you were mentioned in it and you can't forget it even though they both have the nxt day.
