Oh no, now what do I do?

Oh no, it happened.
After surviving Thanksgiving; four scrumptious days off work, eating and drinking nice things that Perfect Husband concocted and put in front of me, a spot of shopping in the sales (Body Shop you complete me...) and a trip to the cinema to see the second in the series of the Hunger Games films (v.excellent, although it almost undid me for a while; first I felt tearful, then I felt sick, then back to tears again, and also most envious of her fabulous dresses- who knew Lenny Kravitz was so adept at designing clothes?) then alas, it was all over and work beckoned.
I don't mind being at work; it's a pleasant little office and the one colleague who really does my head in is on holiday until tomorrow so even better, I just hate the getting out of my nice cosy bed part.
The temperature was a ferocious -15c this morning, and my walk to the bus stop in the dark was not made any better by the fact that I saw that moose and her two (now huge) babies again yesterday, just around the corner from our house.
Thankfully this morning they were nowhere to be seen so I yet live, which is always a good thing.
So there's me getting on the bus feeling all smug that I hadn't got frostbite or a hoofprint on my forehead, when a voice said "Oh I still haven't given you that shirt"....... and there she was, buried under several layers of hats, coats, gloves and carrying a huge stick. One of my crazy lady acquaintances, whom I now know goes by the name of Shirley.
Shirley befriended me on the bus one day, and I chatted back out of politeness, because I don't like to be rude, although really that just encouraged her more. She was telling me about her earrings and I remarked that they were nice (I once had an English teacher who was so old and lined she resembled a used teabag; she was tiny but ferocious, a bit like an old version of myself, and she loathed the word 'nice' because of its mediocrity in the face of so many better and more descriptive words-I still feel a sense of guilt when I describe something as merely "nice") and before I could stop her, she pulled them out of her ears and gave them to me! Sweet and generous gesture though this was....ick! No thanks. Previously she had mentioned that she had a shirt for me and she just knew it was perfect and I'd love it because it had my flag on, and she made me take her phone number so I could call her and we could meet up so she could give me the shirt. Needless to say I didn't quite get around to making that call, so today she wrote down her name and number on a piece of paper and gave it to me.
Now what do I do? It's too bloody cold to walk to work so I am on that bus regardless, and it's only a matter of time before I see her again.
Maybe I should just take my chance with that moose........
