I still haven't come up with a new one, so I will just continue last year's, which was to take more notice and be more helpful to my neighbors.
There are 72 condos in my building. I bought this condo from a man who had been living alone, in squalor, after having a stroke! I felt so bad when I heard his story that I decided to make sure "that" didn't happen again. (I had been living in the same building, about 100 feet away for five years, and had never made an attempt at meeting most of my neighbors. We had to completely gut and redo the condo before we could move in.)
One of the couples (who now live directly above me) was very unfriendly to everyone. I started talking to her every time I saw her. Then I made them cookies. (I told her she was a Massachusetts Snob, she doesn't like anyone! ha ha ha.) She went to the hospital for a knee replacement and I took them up a couple meals. The other day I was up on the second story walkway and her door was open so I started talking to her...she yelled for her husband to let me in. She said "I only talk to people I don't like through the door, my friends are welcome in." (I don't think anyone else has been in her condo...which is beautiful, by-the-way...my ego would have me inviting everyone in!)
Anyway, for lack of imagination in finding a new resolution, and because last year's made me some friends AND made me feel useful, I will just continue it.
