Dear Suginami,
Your title looks O.K. at first glance, but when you questioned your grammar, I decided to analyze your title:
"Is merecedes too troublesome?"
Here are a few thoughts that come into mind:
1. Is - singular, but you have merecedes plural - therefore there is a conflict here.
2. merecedes is plural
3. merecedes is spelled incorrectly
4. Mercedes is a name therefore the first letter should be capitalized.
The title should say "Are Mercedes too troublesome?"
Personally I don't care about grammar, especially if it's your second language. But if you were born and raised in the USA, then I probably would expect more, although I would not hold it against anyone.
Now if you're talking about handwriting...mine is TERRIBLE (haha). When I went to college I noticed most Americans (especially males) have bad handwriting. Foreigners (male and female) and female Americans have very nice handwriting.
Sincerely,
