Paul -
As a general rule -
do NOT trust crew you have known for two seconds with doing your equipment checks, let alone your life!!!
Like I said the above is a general rule but I guess you need to get burned a few times before you learn. It all seems like harmless stuff. "Yeah Paul, it's between you and me..." behind the galley curtain but don't be surprised if you have a guy or girl fly with you weeks later and say "Oh, you are the one that...." Honey it ain't worth it. This industry relies on gossip. Idle gossip is cool but don't make yourself, or anyone else the subject of it. We all get bored in the galley and things will slip. It is all innocent chatter but things get passed on and stories embelished out of boredom. If you don't want the whole world to know something do not tell a soul!
Happy Flying
