It’s what kids at Ingrid’s daycare do in the summer, day in and day out. Just give them a bucket full of water, couple of big brushes and tell them to paint the patio. Or sidewalk or whatever. Bam. Kids gone for an hour. And they can do it again tomorrow. After taking the pictures I just kicked back on a comfy chair with a book. Life was good. Until “Moooooom, Alvar is drinking water from the bucket!”.
