Mobile phone retailers, English and Computer classes, gyms and beauty parlors are all booming businesses in Kabul. You can expect to find one of each in each neighborhood. Of course you can see many more grocers, street carts, pharmacies and barbers but I don’t think these are new.
From what I gather, the weather in Afghanistan is like this: in the Winter, it is bitterly cold and snowy, in the Spring it is rainy and muddy and in the Summer it is dusty and too hot (buildings don’t have AC). I don’t know about Fall so there is still hope.
