so last night i was leading a funeral for my friends cat [laugh if you will] i cast the circle and everything was going fine until a couple guys came and walked right through it. i mean they knocked over the north and east candles as they walked. while my friends forgave them, i got rather annoyed and had to sit down before recasting the circle because i couldn't concentrate. i've seen this happen before when my friends have cast the circle and someone broke it. i was wondering, since we have to use our energy to cast it, does breaking the circle effect the caster, or is it just the person overreacting?
