I have this particular memory when I was in 5th grade. My teacher was talking about how her family and her were trying to brush their teeth the night before with their left hands. She said it was very difficult and some of them couldn't do it. So I remember the next time I brushed my teeth I tried to do it left-handed (I'm right-handed). I couldn't really do it, but after that, I would try to brush my teeth with my left-hand. Now I usually brush with switching off both hands, and sometimes I multi-task so I do something with my right hand and brush with my left hand. I'm ambidextrous when it comes to brushing my teeth. That's about it for ambidextrous talents though.
I found out yesterday why it was a good talent to develop.
Josh was working at a retreat, and I was trying to get Case and I both ready to leave for evening worship. Of course, I was running late on time. I started getting ready, and Case started yelling for food. After giving him foods that he could eat himself, he was still hungry. (No surprise.) So one of my last options was what he was really wanting: yogurt. He can't feed himself yogurt though without making a mess, and with it almost time to leave for church, we had no time for a mess! SO as I brushed my teeth with my left hand while I fed Case with the right hand.
Now I am going to develop my other ambidextrous talents to ensure full multi-tasking abilities. HA!
