I just hate having to move them. I have a small collection of TF's but no permanent spot to have them displayed yet.
Fortunately, my girlfriend's only rule is: 'As long as I don't have them always looking at me, I don't care' and 'As long as you don't care if I move them if they get in the way'.
She supports my collecting and with that alone it's needless to say, I love my girlfriend. I got lucky, I guess.
