Do's and don'ts

Sometimes we do and sometimes we don't. Sometimes we do because we can. Sometimes we don't. Because we can. Sometimes we do because , as redundant as it sounds, we want to, have to, must do. And sometimes we don't because we can't, won't. 

And sometimes by not doing, that is by "don't-ing" we do the most. And of course the opposite is also true. 

We do. Oh dee do dah day.
