Emergency excuse

We have just received an unfortunate and unexpected call that my father in law just had a stroke and Collapsed and he is in the hospital. My husband is taking flight out of state tomorrow morning. I actually don’t know the severity of it and I don’t know when my husband will be back. Could you please take me off the schedule on Friday 22 and Saturday, 23 to be on the safe side. I have to stay home with my kids.
