I created a scrapbook of sorts for both my boys that contain special items or cards that will bring fond memories to them when they are older.
I also have a little box that my youngest made for me when he was in the 4th grade. The box is wrapped and has a card glued to it that says
" This is a special gift that you can never see. The reason it's so special is it's just for you from me. Whenever you are lonely or even feeling blue. You only have to hold this gift and know I think of you. You never can unwrap it, Please leave the ribbon tied. Just hold this box close to your heart, it's filled with love inside.
