For a good cause ...
Recently, I went to a local park in the afternoon to review some materials. At all times of day, people are out milling about, chatting, playing cards, or just relaxing. As soon as I sat down on the grass, a young man approached me and explained that he was a student at a school that trains hairdressers/barbers. He asked if I wanted a free hair wash. He insisted that it would be a big help to him and the other students.
He led me to their school and into their "classroom." After that he took a tiny bottle of water and squirted a bit into my hair and then directly applied that shampoo (I learned later that this is a technique, not an indication that they have a shortage of water) : ). After they washed my hair, they blow-dried it. And this is how it turned out.
Emily almost didn't recognize me. I rode home on my electric bicycle as fast as I could, pleading that I wouldn't see anyone I knew. Sure enough, I bumped into one of my teachers and had to explain why my hair looked the way it did. At least my family had a good laugh about it!
