I was thinking the same.
No one "needs" skis - the first pair, or any subsequent pair. No one skiing is wrestling with the poverty line. So we might as well acknowledge that we do this for fun, and if as second (seventh ... etc) pair of skis is going to be more fun and doesn't interfere with other financial goals, go for it!
One can take this thinking several steps further, you know.
For one thing, in combination, the givens of "doesn't interfere with financial goals" and "no one skiing is wrestling with the poverty line" logically result in
'No one posting here is proud simply because they were able to buy skis X'.
Which leaves the gates wide open for interpretation of motives for posting here. Some hypotheticals include:
'This is a ski no one writes about much; I wish to interact with people who might like them'
or
'Look what I just got, my skiing vistas are about to open immesurably, or at least help me pretend they will'
or
'I' simply can't contain the excitement I have, it's like getting a new puppy only I don't have to housebreak it or take it for walkies'
(I admit that last is the one that I can relate to most, except I'm a rescue animal sort of guy both literally and ski-metaphorically)
