I am going to visit my father in Prague for three weeks at Christmas. I would like to bring presents from Canada for my cousins (boy aged 18 and girl aged 15) but have no idea what to bring! I haven't seen my cousins in over 6 years. I also have no idea what to bring my aunt and uncle or my grandparents. I want it to be special as this is the first Christmas I will have ever spent with them. Any ideas? Thanks so much!
