Going potty through thick and thin

Having just given the patio and path a much-needed overhaul, Mum decided that now was the perfect time to invest in some patio plants. We already had plenty of pots of varying sizes, so that was something we didn't need to think about.

These aren't the real pots, but they do give you a good idea of the size we're talking about. They're nice pots, good to look at and hold a decent amount of plants. Unfortunately, some of them don't have any drainage holes, which is a problem in England.

On one of my recent trips, I tried to amend this situation. I managed to get a couple of holes in the base of one pot, but another was proving to be something of a problem. Even with a masonry bit in the drill, I was only just making a shallow dent in the bottom of one pot. I mean, look at the picture above - you can see they're fairly robust. Not only that, but this one pot was resisting everything I could throw at it with our resources.

In the end, I had to give up.

A couple of weeks later, I was visiting once more and my mum was telling me that she had also had a go at making a hole in the pot - and failed. I went out to have a look, but couldn't find any sign of further hole-making attempts. Moving the pot off the table, I turned it right side up and noticed a small mark on the bottom, inside the pot.

Odd. Why there? I mean, it was awkward to get at and if you did managed to break through, then the table would also be sporting a new hole. I asked Mum about it - this was our conversation...

Yes, Mum.
