19M currently attending a university and i find myself to not have anything going on in my head when i’m having a 1 on 1 conversation. i’m fine in groups of 3-4+ people but when it’s just me and another person i can never think of anything more to say to add to conversation to where i feel like it’s usually just one-sided. any tips on how to expand these skills as i want to be the type of person to where i can walk up to anyone and talk for 30+ minutes about anything
