        عذب الكـــــــــلام

 


معين الكلام    

    
     

                                                                                             


عندما تشتاق

تتمنى أن تنقلب وجوه الناس كلهم ..

وجـهاً واحدا .. لا يألفه غـيرك ..!

لا يشعر به الا وجدانـــك ..!

انه وجه ذلك الانسان الذي سبب لك

هذا الشعور اللامألوف في نفسك
