Mom and I were watching Meet the Fockers and in this movie, there is a child about 18 months old, who uses sign language instead of speaking words.

"It is a smart technique;" Mom said. "The only thing is that when they get to the age of speaking..."

I finished for her, "They won't feel the need to because they can already communicate another way--"

"I should have done that with you!" She exclaimed, interrupting me. "Then when I didn't want you to talk, I'd tie your hands together," she said, laughing.
