I had a friend who's house was completely decorated with pigs, and one who completely decorated with elephants. All their stuff was wonderful and adorable but neither owned a pig nor an elephant. My DIL has decorated a bathroom in cute little frog decor, but, again, does not own a frog that is not ceramic or paint. Back during the duck/goose "country" decorating days, I dare say most of the people who used those decorations did not own ducks or geese. I collect chess sets, but do not play chess...I just like the stone and crystal they are made out of. I cannot call anyone weird...not more weird than me, anyway.
Why not collect what you like?
