Likewise.
I feel the same way. Said as a one-word sentence in response to someone. A: "Thanks for all your input. I'm feeling really confident in our arrangement!" B: "Likewise!" A: "Hi Tom, I'm Mary. It's a pleasure to meet you." B: "Likewise."
Likewise(, I'm sure).
Fig. The same from my point of view. (A hackneyed phrase said in greeting someone. See examples.) Alice: I'm delighted to make your acquaintance. Bob: Likewise, I'm sure. John: How nice to see you! Sue: Likewise. John: Where are you from, Sue?
