I just wanted to thank you again for the great time. I had so much fun with you when we <fun activity>. It doesn't seem to matter if we're being silly or serious, we always have a good time together. Inevitably, I wish that we could get together more often!
I know we're both very busy these days, so I'm touched that you were willing to make time for me. Thanks again for being so much fun to be around. I'll be looking forward to our next outing!
