DEAR ABBY: I am 17. My 15-year-old sister and I know each other's thoughts and feelings almost as well as our own. Unfortunately, we also know when the other's funny bone is "tickly" -- and it starts a giggling fit. When we start, we can't stop.
We get these fits at the most inappropriate times. We are at our wit's end. Can you help? -- GIGGLE GIRLS IN LANCASTER, PA.
DEAR GIGGLE GIRLS: Yes. When you know something is funny, but it is inappropriate to start giggling, the two of you should not make eye contact. That will solve your problem.
