Jammer, my best friend is the same way; a perfect lady. In fact, I've only known her to need a restroom one or two times in the 16 yrs I've known her. BUT, OMGosh!! Every once in a while, she'll "queef" silently. You've heard of "silent but deadly," right!
Up until this year, I've always acted like I had no idea or didn't smell a thing, but earlier this year, it was totally impossible to let it go. I "caught wind" of what she'd done and immediately wheeled myself backward away from her and whispered loud enough for her to hear "Judas H. Priest, Monika!!!!!!"

She turned beet red and went around the corner of the display stand.
Honestly!! I made her walk down an isle and turn two corners so she'd leave it behind her!!! We didn't go back to look at what been looking at when it happened. Also, I haven't let her live it down!

It was a killer!
