I often see the phrase " Dance like no one is watching"
What about the look you see on someones face and the tone in thie voice when they are loving up a pet. It is one of the most sincere things I can think of. How might you phrase something like this?
Dance as if no one were watching. For uncertainty, you need the subjunctive mood. As for “like” versus “as if,” it just feels better to my ear. I don’t remember any specific rule for that.
