6 months ago things were strained with my sister although we were on speaking terms. 5 months ago my dd had a big operation and I told my sister the date of it a month before. So my sister knew about the operation at the time but did not phone, txt or send a card to acknowledge it. This week she wants me to go to her house for a specified 2 hours to collect a present for DD that she forgot to give her for xmas. I said how come she didn't acknowledge dd's operation and she said it was my fault she didn't acknowledge it because I didn't remind her, I suggested that it was up to her to remember things that are important to her and she ignored me. She still didn't ask how my dd was or how the op went. I don't want to go to collect this 'gift', would you?
