While it's too bad that your co-workers don't enjoy perl, so what? You like it. You're good at it. You don't need everybody to like what you like in order to enjoy what you're doing.

It could be nice if they do, but it doesn't strike to me as something to be sad about, really. There bunch of people around. You can't expect them to have the same sort of enthusiasm that you have.

You know, it's sort of like... "There was a sushi chef named Joe. Joe wanted all of the chefs in the world to like sushi.". Yeah, but you know that ain't happening while there are people who say "Raw fish? Where I come from, we call it 'bait'!" :-) ( No offense, just putting it into perspective. )

There are people who also like that which you like. cool. There are people who hate that which you like. But then there are probably millions more people who just don't give a damn about that which you like. Moral of the story, you know you're good at it, so just bone on.
