How did you react when your boyfriend/girlfriend broke the "fart" barrier?

so, it's a bodily function. not the most pleasant kind though =P the first time your significant other farted infront of you (intentionally or unintentionally) how did you react? are you comfortable letting the gas slip in their presence? when my boyfriend farted by mistake for the first time, i pretended nothing happened. and i wasn't grossed out by it surprisingly... haha i guess when you really like someone, things like that just take the backseat.
