Haunting the hood

Despite the fact that the individual in question moved, well his mother moved, a month or so ago, he still haunts the block like he still lives there. The individual is a teenager who hangs out with the crowd of other males wandering the streets. Occasionally, they will hang in one spot.
They used to hang out in the yard of the house where he used to live, but the owner put up a no trespassing sign, well something more detailed than just “NO TRESSPASSING” but with the same gist. This helped when calling the cops because before, the cruiser would slowly drive by, look at them, then speed off. Big whoop. Now the sign is there in the window, they don’t hold court in the yard no more.
Last night they opted to hang in front of B. and IT’s house. I was home playing CIV III when I heard the crowd. I came out because I was concerned. Sometimes B. leaves his bike out on the sidewalk. He locks it, but they were all leaning in the spot where he leaves it. So I came out and decided that my yard needed attention.
I don’t care for confrontation, unless you’re on my fence then I’ll say something, and so I did not speak to the crowd. I just puttered. Visible, noticeable, puttering. If needed, I could have engaged in my impression of loudmouth bubbie lawyer and get on my cell and scream like a crazy person. It is my front yard and I can do whatever the hell I want. Just then some neighbors came walking by, an end to their evening constitutional and we had a chat while the group of young men sauntered away. Seconds later, another neighbor came out and we gave a friendly holler at each other. We stayed out there till the crowd had settled down on the other, deserted end of the block.
