Our father suffered terribly in his quiet way and sometimes in an unguarded moment our normally stoic dad would drop his calm demeanor and his sadness would leak out through his eyes . At 22 , after a tip from a young cousin , I made a few phone calls to a college in the middle of nowhere and told a couple of lies so big even I would n't have believed them to an unsuspecting soul in the registrars office . It worked somehow and she confirmed my sister was enrolled that semester before giving me her home phone number .
