scrap silver buyers in my family

My family consists of many people and most of them are virtually insane. I do not want to offend anyone but my family members are seriously strange. Most of them have strange hobbies. My father for instance likes to collect stamps. It is a rather old hobby and other children can only read about it in the books or see it in the movies. Imagine that my father is actually doing that. He collects all of those old stamps. When my mother once accidentally spilt wine on my father"s collection he got furious but he went to a specialist and managed to rescue his collection. From then he locks his stamps in a special drawer in his desk. My mother is strange as well. She collects various tablecloths. She has half of our garage filled with tablecloths. On top of that, my mother and my father are scrap silver buyers and they actually buy scrap silver quite often. I never really understood why would they do it. I actually never asked them why are they scrap silver buyers as I did not want to make them nervous or anything like that. I guess I was too young to do it. Now I know that it is probably nothing to be ashamed off and I am going to ask them why they do that today or tomorrow.
