You might have happened once you’ve slipped – even fallen or hurt – when he stepped on a wet step.
This usually happens fairly regularly when we step on too smooth surfaces such as ceramic, marble or granite.
It is common for the steps of the entrances to the houses – where they exist – are constructed in such materials. The truth is that they can be very dangerous when wet with rain or wet with morning dew, as one can tread, slip and seriously hurt.
