what do you think about waiting?

I very much hate waiting for people. I am always ahead of time or on time and waiting, waiting, waiting for people. I can't stand it. You should see me at my doctor's office. He makes me wait sometimes two hours. I go crazy inside. Every time the door opens and they start to cal someone, I hope it is me - and it isn't. My older sister is late all the time for everything. I can't stand it. I don't understand why people can't be on time when they know ahead of time when they are supposed to be somewhere.

I hate waiting for people when they are late to the appointment. It is really wasting my time. I will keep calling this one because he/she is late. I have to tell him/her I am very impatient and it's better for him/her to show up soon.
