I told my sister about this so she tried it.
While she had the banana smeared all over her face the neighbor showed up to discuss some repairs she needed to her fence. DS never said a word about having banana on her face and the neighbor was too polite to mention it so they sat and discussed the fence as though the elephant was not in the room!!! Finally as he was leaving DS said she needed to wash the banana off. Flood gates opened! " WHY do you have banana on your face?" She said, "missed my mouth". Poor guy she didn't give him any further explanation.
