You're not declaring it as equal, that would be `==' (or `is' for identity).
`=' assigns, it doesn't check for equality.

Why do you expect "reply is" to happen on the second line? It clearly only
happens when printing the returned value, not when printing from inside the
function itself:

The extra spaces are because "," implies one. If you don't want a double space
before the message, remove the trailing space in the string.
