It was a pleasure talking with you last night at [[event name]]. It was so interesting to learn [[something you learned about that person or their business that stuck out to you]]. As for grabbing a coffee some time, I'd love to take you up on that!
Do you have any availability this or next week? Good times for me are [[let the good times roll here]], but I will be glad to work around your schedule. Let me know if there are any days or times that work for you.
