I obviously don't know who got me, but the person who got me shouldn't worry about it so much. I am very eclectic with my collection and it was hard for me to say my collecting focus, because I am not focused. I categorize myself a type collector because it is the closest to the truth. I have tried some sets but never stuck to one. I have autographs and other memorabila in my collection as well.
I think as long as you put thought into your gift you are in the spirit of the giving and that is all that matters.
