Is sending a “Dear Seller” love letter a waste of time?

It seems 5-10 years ago it was more a common practice for the buyer to try to tug at the strings of the seller.

Today, I advise my sellers to not accept them before we even put the house on the market. Base the decision on the merits of the offer not the buyer telling you how their little ones & Fido & Fuzzball are going to love growing up there.
