It’s funny, and it shows personality traits which are not evident in the rest of her application. Being kinda funny and quirky are pretty good traits, I think. Aside from that, I think that it demonstrates traits like creativity. Moreover, a well-written story demonstrates almost every trait that most colleges want. The ability to tell a well crafted engaging story about a simple Hobby Lobby visit is, I think, a much better indication of a kid who will be successful at college than yet another less well written story about Persevering Against Great Odds.
In my opinion, as relatively uninformed and personal as it is, her essay is what they are looking for. I think that trying to create another essay which “demonstrates positive traits” may come across as more contrived and forced. This story is evidently something that your daughter has thought about and wants to tell, which, I think, will make a much more honest and personal story.
