Alone Together
Come to think of it, alone means you are not with anyone, while together means that you are with other people. It’s pretty funny if you think of it. Well, most oxymorons are as they are amusing since they can be opposite yet there’s a legit meaning behind them that everyone would understand. Like for this one, alone together means that you and the other person or people you wish to be with in private are finally together without distraction.
