Blacklight, often when a person leads a horse by the cheek strap the horse winds up bearing the weight of the arm which makes it uncomfortable behind the ears. Attach your line under the jaw and allow an arm's length of lead. This actually helps the horse not lean in to you or crowd you. By holding the hand close to the clip should something startle the horse and it scoots forward it's shoulder will hit you and possibly knock you down. 3 or 4 ft of lead gives the horse enough room to move ahead without hitting you. Loosie, in North America it's box stalls only for race horses.
