Thank you for your response. But I'm sorry I'm still not clear about the difference between the two.
Let's assume that I'm at home talking to my wife. Since she appears to be tired from working all day, I would like to take her out for dinner instead of her cooking for us, and I say to her, 1. "I suggest we eat out tonight." 2. "I suggest eating out tonight."
In this particular situation, is there any difference between the two sentences?
