when one of the two littlest stands next to me and screams, "mom" and i answer, "what" and then he or she screams "mom" again and i say, "seriously? what?" and then he or she looks at me and says it with exasperation, "no. the pretend mom." and i wonder why they're so caught up in this ongoing game of i'm-the-mom-you're-the-father whether we are at home or in the car or at the fabric store because i am a mom, their mom, and i am with them most of the time and why do they pretend as if they want another mom and why does their little game still confuse me even though it's been going on and on and on and on for weeks?
