New House

Why is it that when you show people your new house, that there are a few who tell you every project that "you really should do" to improve the place or increase its resale value?

While appreciating the interest, it's a bit annoying. Are they going to help you? Are they going to foot the bill? Do they realize that a new-to-you house doesn't need resale value? (Unless you are looking to take a loss or flipping a property.)
