Just what I'd expect from someone
who chose me to be his helper!
!كما هو متوقع من شخص اختارني لأكون مساعدته
Je comprends mieux pourquoi

Non potevo aspettarmi diversamente 
da colui che mi ha scelta come aiutante!
Não esperava menos de alguém
que me escolheu pra ajudar!
Что и следовало ожидать от того,
кто выбрал меня в помощники!
