Every now and then, I have an argument with my siblings about knocking on a bathroom/bedroom door instead of bursting right in. Since sometimes a person isn't decent and it's good manners to knock first before trying for the doorknob. Whereas, they tell me I should lock my door, if I want it to stop because, that's how their generation works these days. Except I refuse to, because I think knocking is more polite under any circumstances. Therefore, I'd like the members on KHI to tell me what they think. And feel free to share stories or anything like that at all too.
