On hen's teeth

Ed: sigh
Tara: ?
Ed: I described something as being like hen's teeth in chat.
Tara: okay
Ed: They'd never heard of it. I said it means rare or impossible to find.
Tara: oh dear
Ed: Then said it was my fault, I forgot they didn't speak old.
Tara: I know what it is and so does my brother Matthew
Ed: Thank you. I appreciate the gesture. (:
Tara: it's true though. matthew used it in his msn name recently. something about how jobs in amherstburg are about as common as hen's teeth
Ed: Sounds about right.
Tara: luckily he got a job at subway
Ed: (:

Ed: and at that point even I noticed I was rambling.
Tara: you're not. this is very goode. good even
Ed: (:
Tara: I was feeling olde-timey ;)
Ed: It's all good, olde-timey people are like hen's teeth. You were saying. (:
Tara: I actually laughed out loud
