In this dialogue, why does Donny say "I would agree" rather than "I agree?" How does "would" works in this context?
Telek's #1: Is there any difference between 'He snuck up on me' and 'He snuck up to me'?
Owlman's #2: I think so. "He snuck up on me" implies that he wanted to surprise you, frighten you, or perhaps overcome you after he got close enough to do that.
"He snuck up to me" implies that he was being sneaky to avoid detection by somebody else, not by you. You might even be an accomplice of his who watched him as he was doing the sneaking
Donny's #3: Yes, I would agree with Owlman's analysis of the difference there
