He's not a physical danger, I could snap his neck, but he plays mind games with those he deems prey, and tries to use his carefully crafted relationship with the landlady to evict conceived threats. He forced a young Irish girl in the flat next to him out through a relentless microaggression campaign, which was the one he took a photo of a teaspoon in a sink and sent it to the group WhatsApp group saying "this must have been someone new, we're not used to this". Everyone was like, WTF?! But when we joked about it, the landlady took his side and said "it's all about respect". The girl who has moved into the same flat next to his, is the one he's stalked. I've made it clear to her what's going on, and actually think I might have a chance with her, so he's gone a bit quiet these last few days.
