Was doing a job for my uncle once was only about 18,a little splash back round his bath and sink,does the job and he asks if i can put up a medicine cabinet for him i said ok but i have no drill he says thats okay just nail into the wooden frame contraption he had above the sink(still dont know what the frame was for)so i does it hangs the cabinet and starts tidying up everything except the hammer which i left on top of the cabinet ,bad move i goes to grab the hammer it slips and in slow motion(or it appeared so at the time)the hammer went straight through the sink,it was one of the old types with a double skin,shouts my uncle he says its okay son will super glue it back together and then proceeds to stick his fingers together 🙂
