I have my most awkward conversations on the phone because people can't see that I'm stuttering so they interrupt me as I'm blocked and it pisses me off haha When I get blocked I'm always silent, I don't try hard to get it out like I used to and people on the phone always take that as silence so they interrupt me. I don't blame them, I'd do the same but it's really annoying. This is why I prefer having conversations in person so they see that I'm having a block and wait until I've said the thing.
