I am not long back from briefly submerging in a silly outfit. It was excellent and I didn't realise it would be so enlightening. I saw such underwater wonders...missing tile grout, a long dead hair clasp, and deeply submerged (well, 2.1 metres) strands of hair that looked just like strands of hair.
I am hooked though. The peace and calm of the underwater experience is brilliant and once I learn to swim the right way, up and not side-on like a fairground goldfish, all will be well. Can't wait until next week. I may bring my grouting tool.
