This is not a current story it's one that goes back some years but I've always wondered about it.
Long story short. Friend in college her mum had breast cancer. I then say well compared to a lot of other cancers breast cancer has a good survival rate(context: this was 90s) . We were walking home. 'Friend' then turns around quite affronted saying implying I'm being insensitive and saying in a huff " My MUM has cancer" before walking off implying I'd said something really offensive!!!! Next time I see her she's distinctly frosty with me. AIBU??
