I agree with you but the second point is actually good:

"When people would begin to interrupt me, I would continue on with my sentence regardless of them speaking, and I would finish my sentence. I would be prepared to let it get a little awkward if they don’t get the hint at first"

I think this one applies less in a friends setting and maybe more in the workplace but sometimes you have to put your foot down and insist you won't be interrupted.
