The thing is that in Ulster at least, the word messages also means.....groceries/shopping.
Yeah, we're a crazy, zany, devil-make-care kinda people ! And probably drink too much Guinness. So lets see a couple of examples shall we ?
"I'm off down the street to get the messages"
"Where's mum" ? "Oh she went into town to get the messages"
And so on.
It must be much more confusing these days though as modern email and Facebook savvy kids would be wondering why one of their parental units would bother going all the way into town just to pick up her messages.
Maybe she left her Eee in Tesco !
