I have 2 good friends who live on the other side of the country.  Over the years we have lost touch just from getting busy.  Last year I mailed each of them a mug and some tea bags that I had.  I enclosed a card saying that every 2 months, on the anniversary date of their birthday (the 8th and the 26th of the month) I would call and we would catch up.  It has been wonderful.  I mark it on my calender and despite needing to change the date or time occassionally, I am back in touch with both close friends.  My one friend told me it was her favorite gift she received last year.
