They let you go home, but remind you to ring in before 9.15 the next day if you are going to take any more time off. Your boss has had a similar thing happen to them. They offer to take you home. You refuse, but they still pop round after work to make sure you're OK and won't hear of you coming back to work until they know you're fine. You're collecting for a colleague's leaving present and taking round their card.
Every human interaction is a learning experience.
I wish you all success in your new job and hope you will enjoy the challenges it brings you. In meetings, your boss Really loves your contributions. But then they love anybody's contributions and are enthusiastic about all ideas, even those that are obviously non-starters. Is always pleased to hear your ideas, but often points out that things have been tried before but didn't work. This sometimes seems like inflexibility and resignation to you rather than experience.
