No one always or never does anything.
People don’t see themselves as one-dimensional, so you shouldn’t attempt to define them as such.
These phrases make people defensive and closed off to your message, which is a really bad thing because you likely use these phrases when you have something important to discuss.
Instead, simply point out what the other person did that's a problem for you.
Stick to the facts. If the frequency of the behavior is an issue, you can always say, "It seems like you do this often." or "You do this often enough for me to notice."
