Been there!! I am a nervous giggler...I remember when my dad was ill asking my priest to pray for him. I was doing my little nervous giggle and the priest just flat out asked if I thought it was all that funny??? YIKES!!!!
I explained that I giggle when I am stressed or nervous...but I don't think he bought it.
One time in college I had to tell about my most embarrassing moment, and giggling in church was it.
Yep, definitely right up there at the top of embarrassments. I still do it from time to time, to the embarrassment of my children. I guess if they had to tell their most embarrassing moments, they would tell about their mother giggling in church.
