Hi,hi.. It's me Rudana. I recommend books so that you can easily figure out which ones you want in your bookshelves. I feel happy as my contribution means something to you.
Throughout these years, you are asking for ways to say thanks to me. To me, there are few easier ways to show someone how much you appreciate them then saying "Book on me" or "Coffee on Me" 😉. It's simple and gets the job done.
