I don’t like people finishing my sentences, and I’m always pretty loud about it, especially because they tend to make wrong assumptions and that can take even more effort for me - by saying “no, that’s not what i meant, please shut the fk up and wait, I’m heading to it”. Or the ultimate pain in the ass - I stutter on the key word, and while I’m concentrating to catch the right piece of breath to get the word out, some smartass decides to finish it with a different (funny) version and that just adds up more effort and more sweat.
