One of my friends asked me a question which still puzzles me. He asked me what the differences were between these sentences that he created:
"I will not leave until I see you start cleaning your room."
and
"I will not leave until I see you starting to clean your room."
It's been three years since I moved to Japan, and my opportunities to speak and listen to English has decreased significantly compared to when I lived in the States. Still, I try to keep my English fluency at the same level as my Japanese. But, both of these two sentences seem OK to me; they both make sense, and it doesn't seem grammatically wrong.
Any thoughts anyone? I'd really like your opinions.
