The dumbest argument I got into

The worst argument I can recall having was with one of my best friends last year. We used too arguing a lot because she would think that I was lying whenever I said I couldn't hang out after I moved. Sometimes I did have to lie to her cause she would be mad if I told her I had already made other plans so I told her that I to go out with my cousin. One time I was really sick so I told her I couldn't hang out cause I was really sick and didn't feel good. She thought that I was lying and saying things like "yea right, sure you are" so that irritated me so I sent her a picture of the medicine that i was supposed to take when I went to the hospital. Then after that she stopped thinking I was lying whenever I couldn't hang out.
