According to your [ubermonkey's] first comment here, you are a "long-term collector of mechanicals." Why do you ubermonkey do that? Isn't that just obsessive hoarding? Why do you keep old things around? Seems obsessive to me.
I mean, what's the point of disparaging someone's pleasures? Can't you just appreciate it for what it is, just someone's interesting, unusual hobby or usage? Can't you give him/her some idea about how to improve what s/he is doing? Or simply leave it alone. Like most moms say: if you don't have something nice to say, don't say anything at all.
