Yesterday, today.

I went to my doctors appointment today. They told me my appointment is supposedly yesterday. What the heck, ive been diet last night and today. They called me last week that my appointment is today. That's what ive heard. And they never confirm me anyway, they just called. That was it. Called one time. How called i be so sure if they won't confirm it. I easily forget sometimes. Then, if i will forget they will charged me $25 bucks. Is that right? So, i talked back to them. I said, i didn't receive any messages or letter in the mail so i guess i am exempted.
