How to get yourself talked about

So, my mentee, who I've been coaching for job interviews, got a great new job. So we went out for a drink after work last night to celebrate. And it was lots of fun, and T turned up. (He's not stalking me, his team were in the pub as well.) And we had a right laugh in the pub, talking nonsense about favourite vegetables and reindeer. And for some reason, (I can't really remember why), he was waving about his keys, which I then whipped out of his hand and pretended I wasn't going to give them back, which included putting them in my handbag. Of course, I gave them back to him later.

Anyway, I ran into him at work today, just next to my desk, and he said (rather more loudly than necessary) that one of his keys wasn't on his keyring, and was it possible that it was in my bag? I checked and of course it was, so I went over to his desk and left it there. And now everyone in my team (and his team) thinks that we're sleeping together. And we haven't as much as kissed.
