One monotonous day is followed
by another monotonous, identical day. The same
things will happen, they will happen again --
the same moments find us and leave us.

A month passes and ushers in another month.
One easily guesses the coming events;
they are the boring ones of yesterday.
And the morrow ends up not resembling a morrow anymore.

Constantine P. Cavafy
