First time

Things which we had each done for the first time recently came up in conversation this morning.
My trip to Sun Palace for the first time two weeks ago to see Deep Purple in concert, also f a first time experience, was ironically their last tour performance in Japan....perhaps.
Akiko topped that story, though, with her anecdote of sitting next to the current yokozuna, who for those of you unfamiliar with Japanese sumo wrestling is the highest ranked wrestler. Visiting a local chiropractor for treatment while taking part in the Autumn sumo tournament this month, this was surely a once in a lifetime opportunity.
Unfortunately, she didn't have the courage to talk to or ask to take a photo with him. Oh, well...
Tell us about a first-time experience you had recently. Or even, a once in a lifetime opportunity that you either took or didn't take. Perhaps, it is something you regret...
