Not to worry, Patash. I live in a very hi SECURITY bldg, and would meet whomever, in the lobby, to assess one s demeanor first. I did this about 35 yrs ago (in another apt), and a group of neighborhood people w/0 heat/water showed up and it was very nice. In a catastrophe, people tend NOT to act Cray Cray. I have pretty good radar, but, of course, I get your drift....
I'm "TINY"aka TheTinyMagic.
BWW log on problems forever. Yeesh.
