I agree with IceBlossom and Onebyone. Make it if you want. Give it to the dad and let the chips fall where they may. At least you made the effort to be neighborly. She might be shy and socially awkward that this would make a difference.
One woman that is in a quilting bee I attend, was never friendly at all. We have opposite political views (I know because I've heard her state hers). I don't do politics at the quilting bee so I decided to kill her with kindness. Every time she walked in, I'd greet her and ask how she was (she has some health issues so it's not just a passing remark) and would react positively to what things she said and I went out of my way to thank her for a suggestion she made that worked out well. She's now very friendly to me. We just don't talk politics which is my stance anyway.
