I’ve had children raise their middle finger to me on more than one occasion. A toddler who got a boo-boo on that finger held it up to show me. A child pointed at something with his middle finger instead of his pointer finger. Apparently we needed to sing more of “Where is Thumbkin?” so he knows which one is Pointer. Of course these hand gestures were innocent. But if a child innocently raises a middle finger in public, most parents would be pretty quick to correct. Ideas can be quickly expressed with simple hand gestures.And it seems the meaning of those hand gestures can also quickly change.
