The thing about your mirror is, you look in it multiple times a day (don't deny it).
So it's the easiest way to make yourself smile- when you write on it...
It's also an easy way to make a friend smile...
...my friend delightfully did my mirror above, with quotes from Cassie like "wow"...and delightful words of "beautiful" and "cute"....just to make sure I don't forget ;)
or what...
