Friends reunited

I had a suprise email from a friend I haven't seen since my teens, he had been speaking to a mutual friend and he gave him my email. So lovely to hear from someone I was quite close to for a time. I had a bit of a thing with him, just our email exchange gas bought some feelings back up. He is 12 years older than me which didn't seem much then but he is now in his 60s, time flies
