Well I could say we will be the ones with the ill-behaved boy that are hunting for a first aid kit or have lost "the boy." (I used to think it was all about parenting until we had "the boy.") So towards the end of the night we will be the parents trying to look like he doesn't belong to us. But we will look for a gaggle of blonde girls. You should move to Minnesota, it's quite common to see hordes of blonde children here.
We adults are pretty unremarkable too, but the girls do stand out. Although they are all ours (combined), I have to say they are all pretty and usually crazy. We stand out wherever we go. Several times on vacation with my husband and my cousin (when her DH is working), we have had people look at us and ask (usually my husband) "Are they all yours?". Sure... Finally one day I responded, "No, we've just been picking up the stray blonde children and no one has noticed yet." The look on that lady's face was hilarious.
