Sister getting similar tattoo

[PaddingtonBearHardStare]

Never posted in here before, just hoping my sister doesn't see it!!

I am getting my first proper tattoo done --ignoring the dodgy temporary one I had done 25 years ago

Anyway I researched on the Internet, found something close to what I want and is very personal to me, I want this on my wrist

Anyway asked my sister to come with me hold my hand and she's now decided she's going to get something almost identical on her wrist as well

I am so upset, I can't speak to her about it for reasons I can't go into it

AIBU to think SIBU?? Isn't that against some sort of unspoken etiquette?

The best thing to do would be to talk to her about it. She probably thinks it’s a nice thing to be matching.

Alternatively get something else after she gets hers done. But then you will still have to talk to her about it.

We were NC for nearly a year so I would find it quite difficult to speak to her without causing an argument
