Opa's little helper

Lana's Dad ("Opa") was working in the workshop/garage and Martin was doing his usual thing - tagging along and providing valuable assistance.
While Opa was busy and being noisy, Martin found the ear protectors and put them on. Of course, he began talking louder because he couldn't hear himself properly. 

Then Martin found a hammer and centre punch and started copying how he had seen Opa work with the tools. Noticing the potential danger, Opa thought quickly,  pulled out his phone and took a photo.
