Not a Harry Potter series fan per se. I used to read the series because Fred and George's characters are inspirational... Not to mention that Snape character. The sixth book was alright simply because of the story line but I really don't like the clichéd hero type stories, and then the seventh book came out and I read it and was disappointed. The plot was slow in my opinion and the character interactions were a little unrealistic. I loved how she made main characters die throughout but the nineteen years later part was what tipped it for me... *shudder* way to clichéd and sappy and such... I'm sure many people agree with me... especially the yaoi and yuri fans out there.
As for this poem thing, can you imagine having another part of yourself who you shared your life with and who complimented you in everyway? You own a business together and grew up together only to have that person ripped away in a very violent manor. Can you picture George going back to their store after Fred died? It's dark and he would walk in and the silence would be pressing in and all of this is happening in a grief clouded mind. He would probably go and quietly make a cup of tea or coffee, sit and watch the fire before climbing into his bed (or their bed... I dunno) and either cry himself to sleep, missing the warm presence beside him or turn over and look at the bed next to his and cry from the empty space in his room and heart. Heart breaking.
