I recently rekindled a decent friendship with a introvert (I sometimes forget she's one) and things has been going well due to our easy going conversations and communication. Or if certain dates are not possible to hang out, we rearrange them for another time. Next week though, she will be joining me on a roadtrip between her and I for 4 days (during her off time) and totally left it up to me to dictate the trip, stated she will go with the flow which kinda surprised me. So r/introverts, have I totally gained her trust in me? Anyways, in what ways do you show to others after letting your guard down?
