i am infj, if my intj friend smiles all of a sudden and then immediately stops smiling is this a bad sign
i went to have a hangout to the mall with my best friend who is a intj, i had a stomachache the whole day and i told her about it but we went shopping the whole day and then all of a sudden i felt extremely nauseous and in pain. she had to stop for me because i was feeling terrible and i had to get out of the shopping stores midway while we were js looking at the clothes around. we found a nearby ice cream stand and she bought me ice cream to try to help me. and i had to sit there for a long while and she js sat with me and we were like in silence. i felt really bad for ruining the hangout and kept looking down at my ice cream, then i looked up, and saw her smiling like this and then stop smiling. I am not ok- but is she okay?
