many thanks for your letter. it was nice to hear from you again. i`m sorry i didn`t answer before, i was really busy preparing for my exams.
as for your questions, you know, i`ve always liked the idea of collecting books at home. i get absolutely excited when i see home libraries at my friends` houses. just imagine, one of my friends has a full collection of exclusive edition of “the lord of the rings”! besides, he`s got a gift editions of “harry potter” books. he likes to collect adventure novels, science fiction and detective stories.
sorry, but i have to go now.
i`m looking forward to hearing from you.
best wishes,
