Why is my mother acting so weird?

my mom is really weird. one minute we are joking around and swearing and sticking up our middle fingers at each other and being stupid and the next minute she is yelling at me for doing that and saying I sound trashy but it was just ok a little while ago! what the hecl can I do so I know if it is ok or not and is this fair?

TALK TO HER ABOUT IT SEE WHAT SHE HAS TO SAY. TELL HER MOM, I'M NOT BEING TRASHY, I'M JUST TRYING TO LIGHTEN OUR RELATIONSHIP BY JOKING AROUND LIKE THIS SO WE CAN BE CLOSER.

Talk to her politely. Maybe she will hear you out. but if she doent continue talking to her politely. It is a matter of time. She will soon realize her mistake.

Good luck!

Maybe she forgets that your not suppost to do that then she suddenly remembers! Lol
but you should talk to her about it!
