1. Evidence of your partner’s name exists somewhere nearby. Your task will be to find it before he awakens, or before he starts any sort of meaningful conversation.
2. Get up and go to the bathroom.
The bathroom is a normal place to visit first thing in the morning, and it is also a place where you might discover his name.
3. Look through the medicine cabinet for prescription medicines with his name on the label.
This is why it’s always advisable–unless you think you’ve found your true love–not to sleep over. Sadly, this has never happened to me. I expect it will once I become an addled octogenarian, but that’s not really the same thing, is it? Has this ever happened to you? How’d that work out for you?
