thanks. I walked in the hall today after putting on blue emu. talk about friendly new yorkers. three new yorkers ,two young ones and one middle aged one came to the rescue and then Zeynep spotted me on the ground and two were able to get me in a cab. my doorman and zeynep got me into the building. after resting the doorman helped me up the elevator onto the floor into my apartment with Zeynep. Cecilia came over later twice.
