Lesson: I Think So / For Me

[english grammar man]

Tokyo is very crowded, I think so.

The above sentence is a common mistake amongst many ESL students.

• When we give opinions, we usually say "I think" at the beginning of the sentence.
  Eg: I think Korea is a safe country.
• We almost never say "for me" at the end of a sentence to give opinions. We could say "I think" at the beginning of the sentence.
  Eg: I think science is very difficult.
