Who's leading who?

Stuck for a blip today as a relaxed morning at home yielded nothing and by the time we did get out the weather had turned. This afternoon I took my horse Johnny for a schooling session with my instructor and youngest went and collected him from the field while I was getting ready to go.

These two have had a special relationship for many years and it always amazes me that this half ton animal will be lead by a small child. Johnny has always been really gentle around my children and they have been able to sit on him, run around him and brush him since they were really little and I have always known I could trust him.
