Personally I go through phases.
One day I am "watering myself down" . Trying to seem normal. Even stupid. And feel almost embarrassed if I "use big words"
The next day I am wearing my intelligence like a frelling badge of honor . Not quite flaunting it or rubbing it in. But using the vocabulary and vernacular I think with (hope that made sense) when it's not always necessary.
Example being using the word scorching versus simply saying hot.

Honestly I rarely know what kind of day I'll have when I leave for work until the right customers come in. (I am the manager at a bar and grill)

Discovering whether or not your gonna be able to hold an intelligent conversation in the middle of a discussion is not fun I might add.
Sometimes my day decides to switch (manic to depressed and vise versa) literally at the drop of a hat.

It's nice to know that I'm not the only one that has those days/moments.
