Non-MT vent

I am posting this here because I know most of you have worked on-site in offices at some point in your lives and I wanted some feedback regarding something that happened in my office.  I used to work as an MT and now I'm in a medical records office with about 10 or so coworkers.  Most of the ladies are nice but there are a couple who like to stir up trouble and one who is a nosy-body and tattletale.  I'm in my 60s, single and happy with my status, not really interested in dating at this juncture in my life.  Today, in the office with about 5 of them in earshot, the nosy one blurts out that she has a male friend who wants to meet someone and would I be interested.  I tried to evade answering the question but then tactfully said that I didn't think it was an appropriate subject to be discussing in the workplace.  I barely know this woman and she knows nothing about me.  I rarely share personal things at work, mainly because I don't think it's anyone's business, and I've always hated people trying to fix me up.  If it had been just the 2 of us and I thought she was a friend or someone I could trust, maybe it would have been different, but I felt that to do this in an office full of co-workers was inappropriate.  Our manager is gone on FMLA and I doubt that anything like this would have been said in her presence but I'd like some thoughts.  If the co-worker continues this, I'm thinking it could be considered sexual harrassment but that's probably over reacting.  It is possible that she is spreading gossip about me.  Then there's the coworker who came over to my desk when I was on the phone on a work-related call, grabbed the back of my chair and turned it in the other direction and reprimanded me to keep my voice down, I wasn't loud, we were conversational, yikes.

This doesn't have anything to do with the above, but late last week, one of my neighbors set fire to his townhouse; he's a cigar smoker and had been throwing his butts on the deck without fully extinguishing them and they finally had enough fuel to start a fire.  There are 3 units in that building and the fire department contained it so it didn't spread, but his place is gutted and none of the other neighbors have come home permanently yet due to the smoke.  Thankfully, no one was injured.  

Anyway, that's my week, any and all comments are welcome, thank you.  It probably seems bizarre, but this stuff all happened. I hope you all have a good holiday.
