Honestly I never really realized how some people will get offended by a person's writing style. :/
I couldn't care less how a person writes, as long as I can understand it's fine with me, rather it's print or whatever.
IMO, I prefer it when a person writes in print, it's easier for me to understand. (Maybe I'm just stupid, I don't know.)
Actually, I can understand the cursive in this comic just fine,
but there have been MANY times where I've come across something that somebody wrote in cursive, and well, it just takes me awhile to understand what they've wrote. (Sometimes, no matter how long I've looked at it, I still can't understand it.)
I haven't really had that problem with print writing though, just saying.
It's fine to like whatever you want, but please, it's kinda insulting to call somebody's handwriting "childish."
Maybe that person just prefers it?
