One of the new things we taught today in trick class was a send away to station next to a cone. Lily picked up the concept quickly, but when I turned around to talk to the class she appeared to forget everything. Then I realised, we'd just been doing it where I point using my left hand, then when I turned to the class I used my right hand. So I tested it a few timed. Lily had really clearly learnt - Left hand point + words = go to the cone. Right hand point is clearly just irrelevant information to be ignored.
