That would be awesome if I had a cool English teacher like that. I've been out of school for a while now, and the last English teacher I had... ugh. What a tediously frustrating woman. I've actually never had a good English teacher. Every one I've ever had has had it out for me.
Well I can understand why they dislike hearing about conlangs because I personally find those of others boring.
Depending on which language(s) the conlang(s) in question is/are based off of, I would disagree. Unless they're based on like, French, or Spanish, or Latin, or some generic language that everyone hears all the time; in that case, then yeah. Conlangs are pretty boring. But when they're based on more exciting, exotic languages then I find them just as fascinating as natlangs. That's why I base my strongest Conlang on Finnish, the most beautiful language on Earth. <3
There is a few conlangs here at this forum that I really like though. Like Karažun. I try not to talk about my conlangs too much. Since I know that those disinterest people much more than natlangs.
But it is understandable that people would be more interested in natlangs than conlangs. After all, who's someone gonna' communicate with in a conlang? Up until recently, I'd decided not to look at conlangs. Not because they're uninteresting, but because I didn't want other people's work to affect my creativity. That way if any of my conlangs were to bear any resemblance to anyone else's conlangs, then I could say with confidence that it's purely coincidental. But it doesn't seem that anyone's conlangs here even remotely resemble mine. So I guess that's all good.
