I might be giving myself away.. However at some brissim I am the only one eating the chicken (even if it is only 7AM)
One of my pals’ dad is a mohel (he is also one). So once he is at a bris with dad, and after the chopping, he is getting ready to leave. His dad pulls two infant diapers out of his black bag, and hands him one saying “take a diaper.”
Friend takes, but wonders what for.
Dad then makes himself a bagel with spread, puts it in the diaper, and closes it up, and tosses it in his bag for the road. Friend follows suit.
