My sister here in Indy has decided that she is going to go out to see my sister in Seattle next week. So me and mom get to babysit my niece's next week while my BIL is at work. That means a lot of my days are going to start at about 5am next week
That will be a nice visit for your sisters and for your sister in Seattle to have someone there, since all of this has been going on with your niece lately. I am sure your niece will be thrilled, too.
I am sure you will have a great time. You always do. We don't call you the #1 ! :-Uncle for nothing! :-D
