I instantly noticed the letters (and numbers) in your doodles. They sort of jump out at you — well at least I thought so. In the super boring meetings, my mind tended to wander, never could doodle since I was usually had to speak, or not to far from those who were.
I remember one of my bosses asked my feedback for the meetings he held. My reply (as politely as possible) was to say that they were pointless, since the plans discussed were never initiated. That boss was a nice person, but his meetings were a waste of time.
