1- You look across the table and tell your daughter to stop argueing with her brother. (Context: You are sitting at the dinner table with your son sitting next to you on the same side of the table as you are, , and your daughter is sitting on the opposite side of the table. Your son and daughter get into an argument about something.)
Can someone just reading that sentence -who doesn't know the context- understand that "daughter" is sitting on the other side of the table from you?
2- Sometimes I look across the office at my co-worker and think: "It must be wonderful coming to work and being completely useless.
When we say "look across something at something/someone", do we strongly imply that "something/someone" is on the other side of the "something" ?
3- The Sun was almost setting and together we looked out across the choppy waters.
What does "look out across the water" mean here? Does it imply that "we" are trying to look at the farthest side of "the water" from us?
