Is it okay if I say I don't have to remind myself of that?... I think rather the effort would be to not assume existence is meaningless in the first place! There's meaning all around - in our interactions with the world and those in it. Just reach out to those near you. Oh, and if you think stutter stop you from doing this... you're wrong. All it stops you from doing is talking with 100% accuracy. But you don't need that in order to be understood. So go on, talk - and stutter! - it's your right.
