ok let me see if i can get this straight...
you are upset about some woman trying to convert you to xianity?
or you want to know if she was, in fact, trying to convert you? and if so, is that wrong or right?
if it's either of those, i think you need to stop caring about things that really are of no consequence. so, you allowed some woman you didn't know to come to your home for a meal... she tried to convert you/acted strangely... then she went home...
so..? what are you upset about? it's not like she's still at your house, throwing holy water on you!
as far as i can see, the wrong was, you let someone you didn't know come to your house for a meal. you're apparently the kind of person who gets a massive bee in her bonnet when others behave strangely, so that wasn't a particularly intelligent thing to do. so don't do it again.
as for the guest, perhaps she was "wrong", perhaps you got the wrong end of the stick entirely. who knows. and who cares??
