What is "1 session"
I have to do multiple sessions to get "the owl" to decrease my number of needed sessions by 1. Can a session sometimes require more than one click on the tree? I've just done about 12 sessions (clicks) and was finally down to one session, and now it's gone back up to 2 and the darned owl is crying again!
I think that the owl is referring to the daily practice sessions, not the skill sessions on the tree. Click next to the owl's ankles to start a daily practice session.
