I have noticed that many INFJs seem to draw odd people to them. This doesn't seem to just be an sexual attraction thing, because they can be male or female. However, if the odd person on the bus is going to talk to someone, you can bet it'll be the INFJ who is minding their own business and not even making eye contact.
This has happened to me while reading a magazine in Costco (by the end of the conversation the very unconventionally dressed older lady who approached me to compliment my purse had drawn me a map of her house and invited me, told me her thoughts on love, and discussed her three husbands without pause. This used to happen all the time during university and also while busking, which are more understandable venues. In later years it has happened less.
I know that INFJs tend to be less immediate judgemental, are painfully aware of being rude to others (even when justified), and have something about them that seems sympathetic. I have had several people have "love affairs" with me that I wasn't aware of at all, until they decided to introduce themselves and console me for putting up walls between us and give me presents!
On the other hand, I have very clear lines and no problem saying if I think something is inappropriate, I am not naive, nor do I make eye contact and smile indiscriminately. I'm not sure if those factors have gotten stronger as I've gotten older, or if I am just out of the venues where they are likeliest to happen.
Do you experience this? If so, why do you think it is?
