How long?

Several weeks ago I wrote 'Love You' on the bathroom mirror with my mascara (Yes I do occasionally wear make up lol) so that when Lloyd got up for work he would see it.

So now the question is, how long do I leave it there? Lloyd wants me to just leave it until it wears away or until we renovate the bathrooms......but I'm thinking maybe I should wash off the mirror at some point....

So how long is it appropriate to leave it on?????
