I'm certain (because I was there!) that they are twins. But other than a birthday, these two have almost nothing in common.
This fact was confirmed when Girly-girl Alice scoffed at Emma at the supper table tonight "I can't believe you wore that t-shirt all day after wearing it for pajamas last night! How gross!" Neither John nor I had paid close enough attention to notice. Oops.
Emma didn't flinch though, just continued slurping up spaghetti and seemed even more amused when Sam pointed out that there was a hole in the armpit.
"Cool." was her only reaction. "Hope nobody noticed at the library today." (me too.)
