Day 2 - Getting myself motivated

Just when I thought I was ready to take on , well, ME, and my past, present and future in all its glory, at least professionally - yes, my CV! - via my tried and trusted laptop I see it. Drip, drip, drip, there it is, a small puddle forming on the ceiling of the downstairs bathroom. And directly above it: the upstairs bathroom.

Upon closer investigation by 1-800-call-Rory, my friend and handy-man, who comes to my rescue at least once a month it is official: the sealant has come away a corner betweeen the tiles and the shower tray and water has been quietly seeping behind it, probably for weeks, if not months, rendering the chip board that the tiles are now barely sticking to, black and brittle. Upon careful prodding (by Rory, not me - though I know someone who would love to give him a good old prodding some time - Mary, if you're reading this, there's no point denying it, we all know! ) some of the tiles just fall away, then some more. The black chip board is as sodden as wet card board. I groan at the thought of the inconvenience and the cost of it all. Now more than ever I am going to need to get a job. We barely have anything left over at the end of a month, let alone anything extra for eventualities such as these. God only knows how long our shower has been like this, and I don't even want to think about the damage between the floor boards and the ceiling below.

When I hang up the phone I can barely hear myself think as the hammering upstairs continues. Tiles crash to the ground, breaking, no doubt, into tiny sharp pieces, making dents on the bathroom floor. Which is timber, amplifiying the noise multi-fold. Aargh!
I need to get out of the house and clear my head. Today was going to be the day when I brought my CV up to date, and tomorrow I was going to start going through job sites. Now, a major set-back. I need to get an idea of how many tiles we need to replace, and then try and find the identical tile somewhere, so that the job will be as cheap as possible.
Try matching a ridiculously-embossed, bizzarly-patterned, off-grey tile purchased, cheaply, no doubt, more than 12 years ago. Needle in a haystack, anyone?
