Yesterday my kids and I went to a bakery. It was hot, they were hungry and grumpy. To take control of the situation I bought some fresh bread. I paid with cash while checking emails on my phone. Then I took the change and started distributing the bribe-bread.
It was after I paid that I realized I should have cleaned my hands before handing out something to eat for my kids (god, I hope my wife will not find this post). I fed my children with germs from the change (to be precise a lot of peoples’ germs) AND my phone (which has 10x more bacteria than a toilet seat, studies show).
