Several years ago I did a 10 week RTW trip. My grandmother was living in a nursing home at the time and I visited her several times a week and I thought she might miss my visits, so I got a world map and marked all of the places I would be visiting. I then sent a postcard from each major stop on my trip, which meant my grandmother received a postcard every couple of days.
When I returned home, I visited my grandmother to find that the staff at the home had put the map up on the wall and had also mounted all of the postcards on the wall with a piece of bright coloured string linking each postcard to the correct place on the map.
The staff told me there was great excitement from my grandmother when she received each postcard.
