That time of year again

The thing I like least about my job might be the fact that it is an elective. That I "compete" with other teachers to have students enroll in my class. Whenever this time of year rolls around, stress comes along with it.
I find that a student telling me, "I like French better than Spanish!" is not the kind of compliment I want to hear. Sometimes, they'll tell me things they don't like about other teachers. It makes me extremely uncomfortable and I never know what to do. I hate that feeling, I hate that sometimes the kids think my class needs to be "fun." I do try my hardest to make it as fun as possible, but it's because I think learning is better fun :)
