I run I jump I am one of four you find me hanging around your door

Answer 1

HELP does not identify the School Subject and you are likely to have no read it. Besides, WHAT is the question?

Guessing it is English and punctuation, here:

I run, I jump, I am one of four. You find me hanging around your door.

If it's a riddle? How about 4 children on Hallowe'en evening?
