The last few times I've seen her on the school run, a friend of mine has been very off with me. She has been laughing and smiling and chatting to others and then just said a very cold hello to me.
I sent her a text after she had been like that a couple of times and asked her if I had upset her, and she sent a text back saying no of course not, she just has a lot on her mind at the moment. I sent a text in return saying I was sorry to hear that and was glad I hadn't upset her and that I was here if she needed anything.
Since then she has repeatedly been cold and offhand with me. This morning she just said a cold hello, and then this afternoon she was walking with 3 others, all laughing and chatting, and when she saw me she just looked, didn't even acknowledge me, and walked off.
I have clearly done something to upset her but I have no idea what. I honestly cannot think of a single thing that I could have done wrong. I feel really upset about this. I hate bad feeling and hate falling out with people and now I feel like crap but don't know what I have done :(
