What does it mean that a man sent me a message saying that he was drunk? What should I say?

As a man, I can tell you that the potential meaning of this short message is "I miss you", because he did not send this short message to others, but to you. Of course, there may be a mass message here, casting a net. Then his thoughts are just expressed through wine, hoping to get your sympathy and further close the relationship.

So, how do you want to answer this man? If you like him, just say I'll pick you up. If you don't like it, you can just ignore it or reply innocently. In short, it is up to you.
