Would you feel weird?

This last week we just found out that the man who we bought our house from misses the neighborhood so much that he wants to buy the home across the street from us that will be up for sale soon(the woman passed away). Some people in our neighborhood have made comments like "oh that will be nice if he buys the house", but Daniel and I are kind of totally against it! The man is kind of wierd (we think). He's a retired LA city fireman so at first we were excited because after he found out Daniel was working for Santa Ana Fire he pretty much told us if we wanted the house he wouldn't take any other offers. But the more we learned about the man, the weirder he seems. Not just because of his purple jeans he wore the first time I came to look at the house or the pink/magenta pair of jeans he wore the second time I saw him at the house! Or the crazy kitchen he and his wife created and were so proud of when he showed it to me. But within 5-6 months of him moving to Texas he came back to visit California and made a stop by the neighborhood, of course. Daniel happened to be outside doing something and he came over to Daniel and made comments on the landscaping we had changed and made some more comments on the house and stuff that he did to it that he's already told us like 3-4 times! Daniel felt kind of weird. We'll since then he's stopped by at least 2-3 more times (in the past 2 1/2 years we've been in the house) to the neighborhood and tells the neighbors how much he regrets moving and wants to move back. Okay so he obviously hasn't moved on with his life. The older woman that lives across the street passed away a couple of weeks ago which wasn't a surprise to most of us because she was pretty old and had to be put into a home, but it was quite a surprise to hear that her niece who was in charge of her estate was going to get in touch with Gary, the guy we bought our home from to see if he wants it! Now would any of you feel weird if that happened to you?? I am just wondering if we are weird for feeling this way. He's retired so he'd be home all of the time and we'd be seeing him everyday! I guess if he does end up moving back I can ask him if he wants his pink stove back since I hate that thing!!!
