They are driving me NUTS!!

Attention, Attention: Somebody has taken my 2 boys and replaced them with 2 CRAZY MONSTERS!!!!!!!!! I am pretty sure their behavior is a side effect of being cooped up indoors due to freezing temperatures, but seriously they are nuts. They run circles around each other, me, and furniture; they climb up everything and jump off anything more than 6 inches off the ground; and they have even started speaking their own language. I think I am spinning out of control; it is so exhausting chasing after them and trying to keep them in line. The worst part is we are looking at almost 3 more months of winter weather, how will I survive with these rowdy boys? Reading books, painting and coloring only last for so long, they have a lot of energy to expend!
