Student or Learner
Can we use the infinitive and gerund forms interchangeably here, please?
"Oh, I didn't see you come/coming".
Thank you very much.
Let's imagine someone puts their hand on my shoulder, startles me and turning around I say : "Oh I didn't see you come" (I would use "come" in this case, am I right? )
If they appeared at my side or even right in front of me without my noticing, then I would probably use "I didn't see you coming".
If I were in a classroom or business meeting and someone suddenly tapped me on the shoulder but I hadn't previously noticed them, I would use "I didn't see you come in" (ie I didn't notice you enter the room).
