granite

the building across the street is dressed in granite. i don't
know my rocks all that well, but I believe it to be granite.
according to wikipedia, granite is one of the most commonly
found rocks on this planet. it's less commonly found on
buildings in this city and you might guess why. our building
(the yellow one), on the other hand, is much nicer. although,
not as nice the one next door.

the keen observer might already have noticed that there is
snow on the roofs. for the record, we're experiencing -7˚C.
