Laura arrived in this city at Christmas. The tree outside her apartment window had lost all its leaves, but the thick snow on its branches gave it a true winter feel. The hands of the clock on the wall turned as time passed, and summer arrived. The tree outside her window turned green. Time flew by, and soon the branches were covered with thick snow once again. Laura spent her second Christmas in the city. When the tree outside her window turned green for a second time, it marked Laura's final summer here.
