Well, let's give this guy the benefit of the doubt and consider that it was meant as a compliment that the entire family likes the quilt. Even at double the size, that many people aren't going to fit under it! Also, "common folks" do not understand the time, effort, and cost of a quilt. I think I'd just smile and nod with a reply that you are glad they like the quilt that is more the size for their littlest one and hope that child enjoys it.
