Getting angry at Mom not understanding two DSC notes are from two different incidents

I'm getting very angry at Mom.  Last year when I was at Disabled Summer Camp,  I made notes from what I experienced when there.   I found my notes and had Mom read it and both them and after I type the notes for a overall leader-  I have explained to Mom twice that two of my notes are from two different days and two different incidents  the only thing they have in common is they have the bus!

The one note is- Make sure we're at the right bus stop-most of the camp we used let's say Bus C,  but for S'mores and swimming part of Camp we needed Bus F instead which was a couple of stops past the main stop.    

The other note is if we're going to be  eating out and are late for the  1st bus the afternoon->evening leader should call the restaurant while still waiting for the first bus and tell them we're going to be late.  Not when we're waiting for the 2nd bus.

She has thought when I showed it to her before typing it up, and  after those notes are for the same day but it's not, they're for two different days.  I was saying after typing I didn't have an explanation for the restaurant late one.  She's asked "Was it because you're at the wrong bus stop?"  And I had already explained it to her once already it was two different incidents. 

So any wonder why I'm getting angry at her?
