What is it about wet concrete that drives people to want to write their name in it for posterity?
It has seemingly been going on since the first concrete footpaths were laid.
Fresh concrete was poured in McNamara Street earlier this week and – sure enough – some mischievous so-and-sos had left their mark.
The name Tyreik was among them. It also featured among the graffiti tags which were scrawled on the walls of Post Office Lane last week.
So what drives people to do it?
Is it our desire for small-time fame, the feeling we’ll never get to put our hand in concrete on the Hollywood Walk of Fame in Los Angeles or do people just enjoy playing in concrete?
It must be a curse for concreters, never knowing what to expect when they return to their neatly shaped curing concrete to find names, tags, love messages and the latest touch, postcodes, drawn deep.
Most of it can be removed before the concrete sets but many remain to be walked all over for the rest of their days.
