Speaking of getting in trouble, hubby and I almost did at church on Sunday, by laughing inappropriately.
The pastor was teaching about having peaceful relationships, and he was talking about not bottling up your feelings. There was a married couple sitting directly in front of us, and we couldn't possibly miss the way the wife turned to her husband, poked him hard with her elbow and mouthed "See? I told you so!". We were already starting to giggle from that, but then the pastor asked, "Do you know anybody who keeps their emotions bottled up?", and the wife's hand shot up like she was Hermione in class at Hogwarts. When the pastor subsequently said, "Whoa, that was a rhetorical question - I didn't really need to see your hands" was when we almost completely lost it.
