Would you take offence to this?

[GVBSJRI]

Met a relative for lunch last week, walking next to her down the road and she grabs my arm and laughs "you've still got your fat arms"

When I didn't laugh along she said "Oh no I'm only joking"

I'm probably about 11.5 - 12 stone at the minute so yes I'm overweight for my height. I had a baby 7 months ago by c section and I still have a fair bit to lose.

I used to have an eating disorder which she knows all about and that comment has triggered me terribly. All I can focus on is my fat flabby arms and how disfusring i look🙁

Would you take offence to her comment or am I just being too sensitive?

She was rude yes, but I'd guess it was more about her being thoughtless rather than being deliberately mean. Either way though it's unacceptable and I hope you picked her up on it.
In your position I'd be inclined to speak to her specifically about this, either a call or in person, whichever you feel most comfortable with. Don't come from the angle that you're berating her, just help her to understand that her 5 seconds of words is affecting you now.
If it's any consolation, I'd guess what she felt was that sense of familiarity and comfort when she squeezed your arm. No judgement, just feeling that she could slip right back into that old familiar relationship even if she hadn't seen you for a while, that everything was just as she'd left it. Maybe similar to her saying 'As soon as I saw that mass of red hair....' etc. I think it came from a good place and when she finds out how disturbing you've found that comment (do let her know) she'll be full of remorse.

Here's my armchair diagnosis - most likely ADHD

I'm blaming the STUPID 'threads like this one' it's a stupid addition & is increasing the number of zombie threads!!

The cheeky twat. I'd have felt like telling her to get fucked

This is the perfect response. Not mean or bitchy just matter of fact and honest. Be armed with it next time she says something rude(if you allow her a next time)

Also, maybe you and your family should start calling her out on her rude comments - every single time, why does she get a free pass? People like this do it bc they get away with it and their victims are usually stunned into silence or too embarrassed to respond in kind.
