Having read through Pasta's link, I'm beginning to think that I've missed out on something!
Some years ago, I received a text message (that clearly wasn't meant for me) inviting me to a party. Not wanting the sender to think that they'd invited the correct person, when they hadn't, I replied along the lines of "Just a text to let you know that you've just invited a very boring, very old guy in Suffolk to your party!". I wasn't expecting a reply but I got a lovely one back, thanking me for letting them know about their error and adding "If you can get down to Brighton, you'll still be very welcome at the party!"
I'm wishing that I'd gone now ;-)
