["Hello! I just got a new neighbor who seems very nice. I have to leave town for a bit, and they offered to watch after my pets. I'm going out on a limb doing this but I've accepted their offer."]
That sounds risky but at the same time if it works out convenient!
I just met my neighbor today. I have to go on a business trip, and they offered to watch my pets while I'm gone. They seem nice and I'm a little nervous but I'm going to take them up for it.
