What's in a name?

How often does this happen to you: You meet someone at a party or work. A few days or weeks later, you run into them again and panic because you have no idea what their name is.

I have come up with a 100%* effective way to solve this problem. And it has nothing to do with improving your memory.

The next time you meet someone for the first time, they will tell you their name. What you do is, tell them that that's your name too. 

New friend: Hi, I'm Bill.
You:  Bill! I'm a Bill also! Great to meet you!

Days, weeks, or even years later, if you run into that person again, they will immediately call out to you using your name, which they think is the same as their name. So, they've just told you their name.

Bill: Hi there Bill!
You: Bill, good do see you again!

[Of course if too many of these new friends co-mingle, you might have some explaining to do but then you can just tell them about your secret technique and they'll admire and revere you for your creativity.]

*Gender-specific names may pose a problem.
