portrait of a stranger

The story goes like this, I was wondering around Air Itam market doing some street shooting as usual as this guy came up to me praising the way I'm shooting. (well, thats a first) while I'm still recovering from shell-shocked, he then process to ask me if I'm able to take a portrait of him. (with pleasure)  

the silent prayer | 550D, 50/1.8

His expression and his hand gesture, makes me wonder what in his mind? praying for forgiveness? praying for peace? ...

On the other hand, maybe I should start doing 100 strangers project... soon.
