Good team training, but some bad staff (at least 1).
Had to get a friend to hear if it was okay, I arrived a few minutes late for yoga, which it was. She has put it all forward to me, so just come in just as quietly. That another colleague then contradicts her is totally faint, because then I was not in good faith. Am so disappointed. Knowing it well is not the coolest thing to be disturbed in yoga, but hadn't hurt any of I had just walked in just as quietly.
