How do you respond?

So I was talking with my mom on Instant message today and she sends this:

[15:22] mom: do I dare take a quickie?

hmm.. trying to think of an answer that would be appropriate

Then I get this:

[15:23] mom: shower I mean!
[15:23] mom: 5 min max


Whew... Saved... I don't have to respond back with an embarrassing message
