My Mouth is Sealed

Sometimes, I'd rather do things by myself. I appreciate other people's help but if they're here just to say a lot of things and criticizing what they see, I guess I have every right to be annoyed or get irritated. I wish I could say this to them, "Okay, you can help but will you please keep your mouth shut?". I know that's too nasty to say that's why I tried my best to keep my cool and not try to talk. I wish they're just here to support not to add a burden at my place :/
