A mare enforces her personal safety boundary by moving away when I arrive. I respect their comfort zone with my visits. Most mares are less comfortable when they have a new foal, and sometimes they are aggressive about getting near. Usually, as the foals get older, the mares become more at ease with personal boundaries for themselves and their foals.
