context: Today was my birthday and I received a card from my friend who lives in India. I wanted to reply to her card and thank her for remembering me on my birthday. As I started writing I started to remember the wonderful time we had together when we were young. I started writing to her about our picnic and the movie we saw together. I started remembering all the things we did together. It made me very happy. I finished the letter and got ready to go and post it. Nowadays most of the people have stopped writing letters. They all keep in touch through emails. Letters are something very personal. We can preserve the letters of our loved ones and some beautiful memories along with it.  Slowly letter writing has been taken over by messages, Facebook and emails, WhatsApps etc. I and my friend only write letters to each other because we feel this is a better way to keep in touch.
question: Why did they hand write the letter instead of typing it on a computer?
reference: it's more special and a better way to stay in touch
candidate: they weren't allowed to
