How did you keep freeze-tag players from standing right by the safe area so that it was impossible to tag them? We* told them not to "guard the base". My children** say:
"One, two, three,
Get off my father's apple tree".
How did you keep the one who is "it" from standing right by a "frozen" player so that it is impossible to "un-freeze" them. We had no special terms that I recall, but my children tell the one who is "it" to stop "baby-sitting" or to stop "dog-guarding".
