Stop finishing other people's sentences

is it so hard to stop this annoying habit? I’m still trying!

but it’s proving difficult. At least I’m aware when I’m doing it, now I need to try and stop it before it happens.

I’m guilty of this. It started out innocently enough. Everynow and then finishing a sentence for someone shows that you are a good listener and that you think alike. I’ve taken it to a whole new level! I guess it’s impatience or something like it, but I’m aware that I do this and I’m going to try and stop it! It’s so subconcious though, it’s going to be a struggle.
