What gift can i give my older brother whose leaving abroad for a few yrs?

Being away from family can be very hard and also very lonely. I suggest you make him something special like a hand made (scrap booking type) photo album with pictures of the family, friends, even your pets. Get the whole family to join in an let each one write a little note and put that in the album as well. I'm sure he will enjoy pageing through it when he feels a bit lonely and long to be home.
