"Do you like kids?"
"If you like kids, you will like this job."
I think what she meant at that time was, kids will be the reason for hanging on to the job regardless the stress from trying to be a facilitator (with good interpersonal skill); a brave public speaker dealing with blunt, outspoken, rebellious audience; a survivor of attacks from viruses roaming the class rooms, a spontaneous entertainer; a merciful, patient mentor; and a well read clerk -- all in one body.
She's right. It's the love for kids that keeps a teacher a teacher. :)
