Rooted!
This box reminded me of a date I was on a few years ago - first part i was pleased with thinking i had probed where i needed to, got the responses I needed and it was going to be easy. As it went on i encountered things I had not done before, learned a few new tricks and spent quite a few moments trying to work out what does in where.
Once I had finished I sat on the couch catching my breath feeling please with myself!
