What can 55 love notes say?

i'm away from my boyfriend for 55 days, so from some ideas online, I decided to leave 55 notes in his suitcase when he leaves, each dated a different date, one for every day he's gone. I just am having trouble thinking of cute th ings to put in each one, little things to remind him of me each day. Maybe something that after he gets 55 of them, can all add up to be something really cute? I'm not really sure, any thoughts???
