Good article, Melanie. We always use initial capitals in the title so that it carries more prominence. I think, after reading your essay, you are suggesting an answer, so your title needs to be more of a statement rather than an open question. You have a good feeling to your writing and it was well thought-out. The only issue I would suggest is with trying to vary your wording. In English, it always reads better if you can use alternative words/phrases as it shows a good command of the language. So, to improve this essay I would suggest it best to try to avoid using the same words/phrases as much as possible - i.e. 'happy' 'good memories' 'create'. It is difficult, I know, but I have suggested a few alternative words/phrases you might use. Hope this is of help.
