It's really not that big of a deal, that's what courtesy flushes are for.
It's part of life. Through the trenches of raising a family, illnesses, life in general, she has seen me at my worst as I her. From holding her hair back while she was ill to cleaning the bed after the unexpected. It is life.
What doesn't kill us, makes us stronger. Same in relationships.
There are much worse things in life. At least you're not on a buddy system while they go do the dooty to ensure they're not eaten by the lions, tigers, bears... hogs.
