Overoptimistic

Me: Of course I’ve set up an account for you. I set up an account for you on every computer I own.
Her: They’re all Macs.
Me: Yes, well, admittedly that’s true.
Her: Don’t you think that’s a little overoptimistic?
Me: Hope springs eternal.
Her: It’s a sweet gesture, but I know you weren’t really serious about it.
Me: *eyes narrow*
Her: *motions over at the terminal*
Me: *face falls*
Her: It’s still running bash. If you were serious, you would have changed that over to tcsh.
Me: Damnit. You’re right.
