It’s a beautiful evening, warm and sunny, and the plan is to go for a swim at The Guillamine out in Tramore. Niamh and her family regularly drive the few miles from their house in Waterford city out to this cove where the swimming is good and, towards high water, you can jump from a high concrete platform into the sea.

There are a lot of people there when we arrive. Far more than I was expecting. Men and women of all ages, with a steady stream of people going down the narrow concrete steps from the car park and back up again.

When we get down to the swimming area, the sea is turquoise and there must be 50 or more people in the water. Niamh’s husband and son go straight to the diving platform.

That’s not for me. Without my glasses, I’m quite lost. I can’t really see where I am and, because I’ve never been here before and there are so many people here and it’s noisy with people splashing into the water, I suddenly feel overwhelmed and scared. I hold into a railing, with people asking if it’s ok to go past me. I let them pass. Niamh is in now, and Lily, and I momentarily think I should just turn back and wait for them up by our towels.

Lily swims back to me and tries to convince me to get in. But I don’t like this. Not one little bit. And why am I here? And this is not for me. Niamh swims over and suggests I enter the water via a hand rail. But I’ve already tried that and I couldn’t do it. She convinces me to try again.

It’s my eyesight. That’s the thing. Because I can’t see anything clearly beyond the end of my nose, I am figuratively, if not yet literally, out of my depth. I follow Niamh’s instructions, and now, in an instant, I am in and swimming away from the shore, away from the gentle waves breaking against the rocks, away from the hoards of people lining up to enter and exit the water.

And it’s glorious. The water is cold, but not too cold. Clumps of bladder wrack float past, dark green and slimy. The saltiness of the sea buoys me up with little effort. How could I ever have thought I didn’t want to be in here? I feel alive alive alive. I think I want to come back tomorrow.
