When I was younger I used to collect postcards, my dad would travel lots when I was growing up but he would send postcards or sometimes take them back for me. Still to this day I always buy a couple of postcards if I go away somewhere. But today with everyone moving away from hand written communications to emails, texts and tweets the ritual of writing postcards when on holiday has died.
You can't stick a tweet to your wall and preserve the memories. We are becoming lazy and too reliant of digital communications - yes it's quick and easy but don't forget the smile you put on someone's face when they receive a handwritten postcard or letter. In today's world it actually means more than you think! !
