SLP friends.,....lemons are your best protection from kidney stones. Eat them, drink water with lemon juice, and avoid tea. When they say that kidney stones are painful, they are not kidding. It's really hard to watch someone suffering from them too and not be able to do a darn thing about it. (Although, they say that roller coasters can help.)
In other news, I have recently found a great oldie resource for those of you that need quick activities for drilling. It's called Practical Language Activities from ECL Publications. I've been using it for grammar practice with some of my older students for push-in therapy. It's a quick way to work directly on skills without needing to haul a bunch of stuff around.
