I enjoy going around Tehran by bus – be it either line 11 (ie. my own legs) or a regular one. As wise people say – you can observe a lot by looking. So what I do is go around town and look. And marvel. This is a sign I saw today when going to Meydan-e Arzhantin:
ورود به کابین راننده ممنوع
حتی شما دوست عزیز
vorud be kābin-e rānande mamnu’
hattā shomā dust-e aziz
It means: no entry to driver’s compartment (so far nothing special) even (for) you, dear friend.
Adorable, isn’t it?
