Twig! You've been showering for hours. Tryouts for the musical are today. I have to look fabulous! Think of the environment! I've got it covered! Oh really? Really. I'm not showering for three days! He's my carbon offset.
So I'm "cheap." It's a perfectly good word. And it aptly describes my interest in conserving resources. I suppose we could call you "thrifty." Heavens no! And waste two whole letters? I see we've only wasted one whole tea bag.
Your showers are way too long, Twig. You should try taking a shower. Unlike you, I refrain from wasting our precious supply of clean water. Oh? Sniff. Clean air is important too, you know.
