سلام
كجا داري ميري ؟؟؟
تازه بهت عادت كرده بوديم
تازه داشت يواش يواش دوقرونيم در مورد نوشته هات مي افتاد
خوب ميدوني جيگر !!!!1 رفتن انواعي داره
مثلا رفتن به دستشويي ، داروخانه ، دكتر ، دانشگاه ، يه كشور ديگه ،
اون دنيا !!!!!!!!1
نميدونم كدوم بري ميخواي بري ؟؟؟؟
فقط اميدوارم اون دنيا نري !!!!!!1
هي يه دقيقه صبر كن
نكنه ببندي ؟؟؟؟
ميدوني چيه ؟؟ بعضي وقتا آدمو نگران مي كني
فكر كنم اون ناپروكسنه يه خوره رو مغزت اثر گذاشته
...
نميدونم اما فكر كنم بيشتر رو ملاجه من اثر كرده
من از رفتن خوشم نمياد

Origin and discovery
