I believe it was Arthur Clarke who I heard speculate that we may have already encountered other sentient life and just not recognized it. If something lived so slowly that it took decades or years to form a coherent thought we would never have the patience to talk to it (even if we could figure out how). If something lived so quickly that it was here and gone in a day it wouldn't have the patience to talk to us. For some long-lived species a trip between stars that lasted a thousand years, to us essentially an impossibility, might be the equivalent of an evening parking on Lover's Lane.
