Sekadar nota untuk aku…takut aku lupa…aku mudah lupa…biasalah…manusia selalu lupa…lupa diri…lupa asal-usul…hanya kerana nila setitik…rosak susu sebelanga…pepatah ni ada dua perspektif…contoh pertama…jika terdapat seorang yang teruk perangainya dalam satu kelompok manusia…maka ia akan merosakkan yang lain…contoh kedua…jika terdapat seorang yang teruk dalam satu kelompok manusia…maka yang lain juga akan dipandang teruk…namun yang memandang tadi kadang-kadang lupa…yang dia hanya paku dulang paku serpih sahaja…dia lupa satu jari yang menuding lagi tiga patah balik dekat diri sendiri…aku yang menulis ni pon kadang2 lupa…jangan nak diajar buaya yang dah pandai berenang…kelak seperti anjing menyalakkan dinding sahaja…tapi apa nak buat…ditelan mati mak diluah mati bapak…disimpan aku yang mati…mati akal…

When you say “I Don’t Care!!!”, you don’t have to think about it, you don’t have to say about it, you don’t have to write about it. But if you did, your “Don’t Care” is not “Don’t Care” but it just your Stupid EGO.
