Trying to "kill" someone's attitude

with kindness is difficult. 
There is someone I know who is not an easy person to get along with but I need to get along with this person. I do get along with about 99% of the human population. We might not be friends but I am civil to them and they are civil to me.
There have been a few, a very few, people who have been rude to the point of being thoroughly obnoxious. I have avoided them where possible.  I have been fortunate to count among my friends people from an incredibly diverse range of backgrounds and beliefs.
There are many others I consider as casual acquaintances. We rub along like most other casual acquaintances. We say hello or exchange a remark about the weather or even just nod an acknowledgment.  I talk to their dogs tied up outside the library or where I park my trike at the shopping centre. We might have a slightly longer conversation waiting for a train. 
And then there is this lonely person. I have mentioned her before. We both belong to the same group. I have written about her before. Lately she hasn't even been ready to acknowledge me, indeed has gone out of her way to ignore me. I don't know what brought it on and neither does anyone else. We have a theory she may have forgotten something she was told months ago and found herself in an embarrassing position because of it.  As we both belong to the same group it has been difficult. It has been difficult for everyone, not just for me. 
As regular readers of witterings know, I did some baking on Sunday. I made the Christmas cakes. I wrote about giving this person a small one. And I did. I packed it  up with some shortbread and something I hoped she might enjoy using. I put in a little note saying we would like to see her yesterday. She didn't come and I will admit I was disappointed. Perhaps I expected too much. She hadn't even left an email to acknowledge she had received what I left for her. I tried shrugging and telling myself I had tried - and trying is surely what counts?
This morning I removed some advertising literature from the letter box and, underneath it, there was an envelope with my name on it. Inside the envelope there was a proper little note card with a very  brief message. 
It's a start. Perhaps we can move on from there.
