What's the problem?

I had to get up early in order to go some places, I needed to be out of the house by 8:30-9:00 AM. When I got up at 8:00 I got dressed and was ready to go. The person driving me (My Mom) was mad only because I got up a half an hour late, but she said she would not take me, and it just happened to be the day I was getting my permit for driving. I will not tell you my exact age but I will tell you I am too old to not even have a licnce. So I began to freak out trying to give good reason to go and get my licence. I told her we should not fight about something so small, but my Mom had. I love my Mom but sometimes she can really be earating.
