Booking on behalf of relative? Is this a weird situation?

Hi all. So I have an upcoming meet and greet for a potential house sitting job that I want to ask questions about. The initial message came from someone in New Orleans and I live in WI. I told them I was sorry and that my gps was maybe confused or something because I had literally just got back from a visit to New Orleans.

Instead the person is communicating with me on behalf of their elderly father who lives in my city. His father wants to travel over Thanksgiving and needs a sitter can't use Rover himself. So the booking will be through the son's profile who is paying for the service, and I'm setting up the meet and greet with the client through the son.

Does this sound normal? I feel a little anxious about it all and I don't really understand why exactly. I can't articulate what my fears and concerns are really. All the messages have been normal and no flags have popped up.

Advice? Thoughts? Experiences? Any and all comments are appreciated.
