<Recipient Address Goes Here>
It seems like ages since we've done something fun together. We get so busy with our lives that before we know it, months have gone by since we've had a <day/night> on the town. If you're going to be free on <day or date>, let's <description>. If there's something else you've been dying to do, though, I'm certainly open to suggestions.
Give me a call or drop me a line and let me know if this works for you. I can't wait to hear from you.
