We're Irish you know
(Among other things.)
Liam is an Irish nickname for William and Nathan looks like the family tree stopped with his Irish great great Grandma Burke, so you'd think that they (or we) might have some Irish pride.
Alas, on this "wearever" day at school, when the kids didn't have to wear their uniforms and could wear whatever they wanted as long as they wore green in celebration of St. Patrick's Day, Nathan's only green shirt (that's not a polo and thus a shirt he can wear to school any day) is a practically brown green. Oh well.
It's a Christian school, maybe he'll actually learn something about St. Patrick today that will be worth celebrating next year. (Not only do his parents have no sense of cultural heritage, we also don't drink beer.)
