Yes, I agree with Jory. I have trouble saying these meaningless social expressions. Sometimes I just forget, because I am not really wired to remember trivia like this, and part of the time it's because I don't actually feel the feeling at that moment that would go with the phrase. But even when I have the feeling, I have trouble with the phrases, as they have such an artificial sound and feel to them, which makes them feel wrong to use. I also have trouble buying greeting cards for the same reason, as the sentiments expressed usually either don't fit, or, like in talking, feel so artificial and fake. They are basically used as social conversation keys and fillers, which are expected by NTs. If you don't use them enough the NTs get bent out of shape because you are not using the social codes enough.
I do try to use them sometimes, and I am okay with holiday greetings, but I don't see a real solution over all, as NTs do expect this stuff, but to me it's usually just useless and unimportant trivia.
