Weird person on my block

It is a weird boy on my block. He is really creepy. He on somebody that lives in the house with him him is always at the window either in the front or the back. They just look down at you out of the window and stare. They don't really say anything until you look up and find out that they have been looking at you the whole ten to twenty minunets that you have been outside. They are a little scertive but they business still be out in the streets cause they are loud when they are drunk and under the influences of what ever kind of drugs they have in that house.
