Because you both make me laugh. Every day.
You drive me crazy, too, but I think it's part of the Kid Manual that you do that. You are stubborn and sweet, achingly tender and outrageously catty, and either one of you can wind the other up in a heartbeat.
(That does get a little tiring, actually. Just an observation.)
You're loyal to a fault and smart and compassionate, with great big hearts
that you use to teach me new things all the time.
I love being around you. Thanks for being my kids and calling me Mom.
