Let me back up. My sister has been dating a guy named Joe. She went to Australia for Christmas and was in a rush before she left, so she asked me to drop off a little gift for him that she bought.
Yesterday afternoon I went to his house and knocked on the door. A very pleasant, 30ish blond woman comes to the door. Immediately I think, "Oh no, is this is ex-wife, here watching the kids? This could be really awkward." In fact, I tried to think of something I could say so I wouldn't have to leave the gift, but I'm just not that quick. So here's how the conversation went:
Me: Hi, is Joe here?
Ms. Pleasant: No, he's not.
Me: Okay. My sister wanted me to drop this off for him. Would you give it to him?
Ms. Pleasant: Sure. (with just a hint of a question mark at the end of "sure")
So I immediately go home and email my sister so that she knows his ex is currently reading her card.
Of course she immediately emails him and asks, "Is there any chance your ex was at your house today watching the kids?" And he responds....
"No, but it is a funny story. Your sis got the wrong house but just happened to go to a neighbor's house whose husband is also named Joe.
The poor lady thought her husband was having an affair and that your gift was from a mistress. She finally figured it out after she got herself off the floor."
