Dear Aunt Fern,
We did receive the email that you sent to us the other day regarding the possibility of us moving to Country A. I'm not sure what information you were trying to give us, since your email focused on Country B, not Country A, and the jobs we are applying for are in Country A. We'll be sure to let you know if we need any help at a later date.
Possibly too cold, but I would be really irritated by this person telling me what I should be doing.
My grandmother has a similar habit, of giving opinions regarding certain nationalities, except that her opinions were all formed in the 1970's and 1980's, so a lot of it isn't relevant anymore. For example, she lived in Berlin, Germany while the Berlin Wall was up, and her view of German society is based on that very fractured viewpoint. I disregard almost everything she says regarding "all Germans", due to that.
