We didn't:
- Fall overboard (yay! Although it was a close thing on a few occasions, especially when swapping punting shifts)
- Overturn the punt (see above)
- Catch Weils Disease (hopefully)
- Get beaten up by a swan (despite its terrible death hiss, and the evil look in its eye that said "I'm a beyootiful bloody swan, me, so gimme some fuckin' bread or I'll peck yer eyes inta the backuv yer skull.")
- Get tangled in angling lines (but only because they saw us coming for about twenty minutes, in a delightfully meandering route, and sensibly removed their lines from the water before we got there)
- Lose the pole and have to paddle our way home (but there was a couple of hairy moments when it nearly came down to a decision whether to hang on to pole or boat)
- Go very far
We did:
- Buy a tacky straw boater (to protect me from the sun!)
- Get up close and personal with every patch of nettles within a quarter of a mile of the boathouse
- Zig-zag wildly from bank to bank (punts crash with quite a thump, it turns out)
- Turn sideways and block the entire river
- Crash into other punts
- Have other punts crash into us (we weren't the only rookies out there)
- Go backwards, sideways, round in circles, and every other damn way except straight forwards
- Almost get the hang of punting (about an hour and 45 minutes into the 2-hour trip)
- Take lots of photos (still haven't found my camera lead, but that's probably because I've not really searched for it)
- Have a fantastic time
We scrabbled our way back to the boathouse, under the cynical eyes of a lot of very tall young men who were clearly all experts, and staggered to shore and safety. To his eternal credit, when one of them asked him how we'd done, A said, "You know, the moment we got out of your eyesight, we did brilliantly!", and got a laugh. Thus we arrived back with style, if not dignity.
And then we went home and I fell asleep for three hours because I was exhausted, and then I woke up and we had taco punts (little taco things shaped like trays - I just found them the day before!), and I made a rose-flavoured cake which involved ludicrous amounts of icing, and we had Champagne, and I think A had a lovely birthday.

As much as your story makes me want to try punting just to see how terrible I'd be at it (and how much fun I'd have in the process!), I think I'll stick to kayaking. I'm fond of keeping my center of balance a little closer to the water line - helps with the not tipping over and all ;)
And, hey, I didn't fall in, and I'm not famed for my steadiness, so it can't be too bad.
I must try kayaking if I ever have the opportunity. It sounds very exciting.
