Thx dude, No, there isn't noboby who lives in my neighborhood. The funnie fact is than my home is in the middle of Buenos Aires and my university it's in a more dangerous place . Thanks man, Excellent quote! Hand to hand it's a really last option... before that, it's Hand to "glass, bottle, stick, piece of wood, brick, stone, chair, even a grandmom (joke!), or a bazooka" what it's closest in that situation. Thx to all for the nice messages!
