This weekend, I was with my sister (we are both around 25 years old and I'm the youngest). The first day, she learned something about me and started teasing me about it.
The second day, we were cooking and the subject of the teasing came back. I knew she was going to make a joke about it again, so I said "No" but she made the joke anyway.
I then decided to leave the room and let her cook alone to show to her that teasing me about this was really not nice. I verbally express my displeasure:
If you want to be annoying, I don't have to listen to you!
I came back less than five minutes later because it was important to do the cooking and because, despite the fact that I hate cooking, I was feeling guilty about letting her cook alone.
In any case, she did not tease me about this subject afterward (and I believe she won't do it again in the future). However, I'm wondering:
Would have there been another way for me to strongly express that I don't want to be teased about this without having to let my sister cook on her own (even if only for five minutes)?
Please don't suggest that I kick her out of the kitchen to cook alone, that would be an even worst solution for me.
Notes and clarifications
The first day, I didn't tell my sister that I found the jokes hurting. I was just trying to "defend" myself and I was not laughing when my sister and my cousin (who was there) were laughing (but I might have been nervously smiling).
Also, when she was teasing me the first day, it was late and I was tired, confuse and unable to think or even realize that I found the jokes hurtful (I'm on the autism spectrum and I sometimes need time to understand how I feel and that something is making me feel unwell).
The teasing was done in a good spirit and I wouldn't have minded a little of it but, at some point, it wasn't funny anymore.
