Pretty much the main few things, most of them you have already. - Finishing off a sentence is a sin. The feeling is indescribable. It's probably the worst feeling I've experienced. It just makes you feel inadequate. - Don't offer tips or advice, especially if they're general like "slow down", we don't take kindly to that. - Unless you really do stutter, as in suffer from constant stuttering, don't claim "i stutter sometimes" to your partner, a lot of people I know say this, yet they don't, and it just makes me want to explain to them the difference but it never works. - Don't focus too much *on purpose* on paying attention when I'm talking, it makes it awkward and feel like I'm forcing the person to really care. - If we tell you we can't order something, or don't want to talk to someone, please listen. It's not as simple as "just go up and order it, everyone else can". It's like telling a paraplegic to walk slowly. - Please do not say something like "oh you're not stuttering today!", because it will just make it feel awkward. Also I don't know if this applies to everyone, but I hate when the word stutter is thrown around, it makes me actually shiver. - Pretty much staying open minded really helps.. just showing general support is always good, showing compassion. I think having a stutter has really made me appreciate compassion and friendship because to a lot of us we lack that. Pretty much your compassion will mean 10 times as much compared to someone who doesn't stutter. - Most importantly.. never use it against someone in a heated moment and apologise later, because I/we will never, ever forget. I'd consider myself very forgiving. Cuss me out and pin me against the wall and if you're down to get smashed with me an hour later and shake hands over it, drinks on me, but if you insult someone about their stutter, I/we may forgive you, but that'll always be my first thought of you. Pretty much whenever I think of some of my old schoolmates, the first thing that comes into my mind is the time they mocked me rather than anything else. Pretty much a stutter is a massive mental battle. It's more mental than physical, even for those with severe stutters. I'm a covert stutterer, and I went through up to a years work in different places without anyone noticing that I stuttered. They just thought I was a bit shy sometimes. Your partner may be a covert stutterer, not sure, but even if he is, everyday just like the rest of us he is still facing a huge mental battle, so try not adding a lot of stress onto the relationship. Treat our fellow stutterer with care, good luck :)
