I think someone is following me...

Yesterday i went to my work, but on the way, i heard steps behind me. Ok, it's normal... is just the street...but i felt how someone was looking at me and, when i turned around, for a split second i saw someone's foot behind a wall. THAT WAS WEIRD. i just want to... live a quiet life... i deserve it, right?

Anyways... i dont know how to use this, i dont even know what the hell im doing now, what iS THIS??
