I like Rockheads suggestion, although it could be a sexy piece of lingerie too.
But other than that, idea's that come to mind include :
- 3 little objects (or an object with 3 parts) that represent : your first meeting, the time you spent apart, and your reunion
- a pressed rose (if he has any sort of diary or the likes, he can keep it in there)
- a cupcake (trust me, we like being given things you've made for us, especially little food treats)
- Where something that he can take off in public (eg scarf, glove) and ask him to take it off...have a glint in your eye and tell him that's only the first item/thing/beginning
- If you're wearing long sleeves, you can write something on your wrist , and keep revealing your wrist to him (He'll eventually see it)
If you are picking him up in your own car, you can put together a CD to play in the car.
As for when you get home, have the first day planned out for him. And have music for when you get home at night.
Ie...it's about thoughtfulness, and the little things that you do.
