Dear Bob,
I was wondering. What should I buy you for Christmas? You have never been talkative, therefore I do not really know what you are interested in, but I really want to make this Christmas special. You are one of my closest friends and I should feel ashamed for asking you this but what Christmas present do you have in mind?
Should I buy you board games? I heard you love chess, although I find it really boring. Or maybe some magazine editions that you are afraid of asking your parents to buy? I am also thinking about colouring books which help people get less stressed but you are always as emotionless as a rock so I do not think that would be a problem. I am so lost.
Please email me soon,
Your friend
