..because they'll both get fussy and start kicking each other. They'll each have less than zero patience. Then when you finally get both of them happily eating, one will mess her diaper...and you'll find yourself wishing you were a hindu deity (ya know - the one with 6 hands). So you'll listen to one scream while the other eyes you suspiciously. Finally you'll give in and change the diaper while they both scream. By the time you're done they'll both be fed, but neither will fall asleep because they'll be too worked up. So you'll go back and forth between the two, rocking/burping/inserting binkies....and then you'll get a sudden craving for a turkey sandwhich (and you'll be grateful that your mom left a jar of turkey meat in your fridge). and then you'll find yourself online...blogging instead of trying to squeeze in an hour of sleep cuz you can type while you're chewing your food...and you'll decide you must be crazy...but atleast you won't be hearing non-existant music like the previous night....*ahem*...and then you'll look down and realize that you just gobbled up a whole pack of red vines...or maybe the music faeries stole them. yeah. that's it.
so anyway...just don't even try it. ummm...amen.
