see someone off—
1. bid a person goodbye at an airport, train station, etc.:
- The decks were crowded with voyagers and those who had come to see those voyagers off.
2. (coll.) force a person to go away:
- I know an audience of stuffed shirts when I see one. Besides—I just had to see that pompous bastard off.
see someone out—
1. take smb. to the door or exit:
- “Did you leave your key with them?” “Yes; the maid who saw me out, took it from the door.”
2. (euph.) survive a person:
- My dear wife is, I fear, frail in health—though I trust and pray she may see me out.
3. outlast smb. in a drinking contest:
- He could see the Dundee people out any day, and walk home afterwards without staggering.
