I have friends I've talked to for close to days worth of time in voice and text chats in groups but 1 on 1 I can't talk to them at all or keep a conversation going. I have another friend I can talk with for ages when I meet him but when we talk 1 on 1 over text it's a bit more difficult to keep it going. Right now though, we're talking over text in a group with 1 other friend who's currently asleep and it's easy to keep it going. What do you think causes this? I feel like there's some term to describe this but I'm not sure what it is.
