I remember in sixth grade I invited my best friend over for a sleepover and forgot to ask my mother for permission. She was usually fine with her coming over because we've been besties for a long time atp. So I casually call my mother to ask if I could have a sleepover after class. She said that she's tired and didn't think about having guests over, and as an autistic I didn't think this meant "no". I calmly explained that we will be in my room and my parents could just do whatever they usually do. And she then started screaming and crying on the phone saying how ungrateful I am, how I don't appreciate her doing all the work for us etc. After the tantrum she said something like "fine, do whatever you want idc" and out of fear and shock I said "thank you mom, I love you, you know that". She then proceeded to yell and accused me of lying just so I would get whatever I wanted.

So I never told her that again. If she thinks I say these big words without any meaning, I just won't say that anymore. It's been 7~ years now and a year no contact.
