Sounds like you did nothing wrong and you just bumped into one of the endless disasters in the park. World is full of people who are a good few sandwiches short of a picnic. Nothing is their fault and if you happen to be nearby it's going to be yours. Yey \o/

Do ignore them dear. You need a thick skin and some liberal use of the slap emote. Or my personal favorite just irritating them even more with a ridiculous level of polite antagonism. Healer or not, there ain't no cure for someones stupid.
