This is how it went:
Me: "Caleb, don't lean too far over the edge my love, that water is dirty, and you don't want to fall in".
Caleb: "oooooh Mom, I am not a baby like Daniel, I can take care of myself".
Me: "Ok Caleb, but if you fall in, you know I am not coming in to get you.. who knows what is under that water".
Caleb: " Yeessssss Mom... 'sigh'".
10 minutes pass...
Splash.. followed by screaming.. high-pitched distressed screaming...
Caleb: "Mom.. sob sob sob.. hurry.. come get me out before something bad gets my feet.... sob sob scream sob".
I run over.. naturally.. haul him out.. he is wet up to his armpits..
Sitting down on the grass 5 minutes later.. hugging my "big boy" to my chest.. rocking gently..
Me: "Its ok my love, nothing got you.. and Mommy came to save you quickly".
Caleb: "Sob.. thanks Mom".
Me: "See my boy.. sometimes Mommy says things for a reason.. not just to spoil your fun".
Caleb: "Yes mom.. sorry Mom".
Ahhhh.. another small victory for mothers everywhere!
