I just dislike how some people seem to use it for nearly everything, ignoring every other font in existence.
Yeah, this happens to me at schoool. It would appear English teachers are particularly fond of Comic Sans for whatever reason. (It's in every damn handout >: )
I don't really have a favourite font when it comes to writing essays. I just stick with whatever the default MS Office uses. (Callibri is it?)
Personally I'm quite fond of fonts where they have curved ends. (like Century Gothic) Not realy sure why, but it just appeals to me as it looks pretty modern or something. I like Helvetica Neue Light too, it looks really neat on things like on a lockscreen clock.
