Grand day, grand flight, you did very very well to make such good use of conditions and companions in flight!
The one who went by you giving a wave was doing the proper acknowlegement that you have been seen and appreciated! I'm sure he thought you were really a glider pilot, though only flying a Robin; the powerful Robin is often in use as a glider tug, and the tug pilot needs to understand how to find lift in order to give best launches.
But why have you waited all these years to fly a real glider? doesn't need a lot of money, a half share in a decent 40 to one club class competition glider could cost as little as £6 or £7 G. Only takes 15 minutes to rig or derig, kept in its roadworthy trailer, could stay in your drive, or at low cost at the gliding club; think of the hangar charges you save!
And best of all, you have mates to share your gliding stories with. I am still flying at 81, several older than me are still tooling around the sky. We don't get bored, every day is a different challenge.
