>>3441381fun, being a post-event subjectification of an action, cannot describe a state of "being" though it can describe a state of "having been"
furthermore the constant flux of time even while she is continuing to speak the phrase implies a progression away from the state which could be described as having possessed a quality expressed as fun
that is to say this sentiment would be essentially true if she had said "fun things -were- fun"
but she did not and thus the image is inaccurate
