Yup, this is exactly what I'm talking about. Adding to your example, a lot of XLEs like to make people laugh when they want to, injecting their own Fe into the atmosphere in a sense. And from what I've seen, xEE types enjoy taking on projects of their own sometimes and like to share their knowledge and get stuff done (Te). It won't ever be as strong or as available creatively as the creative function, but from behaviours like all of these things mentioned, it makes the HA function in practice act like a "lower level" or "lower tier" creative function.
