May "Standing across from someone" mean "being in front of someone"?
Is there any other meaning for this?
It does mean in front of someone, but makes us picture a space or an obstacle between the two, such as a street, an aisle, a table.... whereas "in front of someone" implies no such space. You could kiss someone in front of you, but if they were across from you, you'd have to throw them a rose.
