kids with sitter keep phone available!

RANT

came to watch the kids yesterday at 1 pm parent ask if I can sleep tonight I said yes she said she will be back by 1 a.m. I stopped counting my hours when the parent arrives when I get to the home the parent informed me that she will not be coming back that night that she will be coming back the next day that was not the agreement so i continue to count until the parent is back if she informed me or not..

ISSUE! Walking around and dealing with the kids yesterday I I pulled something like the back of my ankle and lower calf it hurts like hell I cannot walk at all I literally have a plastic sandwich bag with ice and plastic wrap around it I need to go to a hospital and I have tried to reach the parent I texted /called her this morning around 6:20 a.m. and its 9:30 and I have not heard back from the parent i also contacted everyone that's with her 3 phones

The kids are small three years old and autistic they cannot do things themselves and I cannot walk!!!

I understand you want to get away and have fun and not have to deal with kids for a few hours but you do have kids and then in case an emergency you need to keep your phone on and answer it!!!

PLEASE IF YOU LEAVE YOUR KIDS WITH A SITTER ANSWER YOUR DAMN PHONE IF SHE IS CALLING IS BECAUSE ITS AN EMERGENCY!!!

am i wrong to be upset?
