Provide the theme summaries for the following conversation: 

Luke: wow I got my ass kicked surfing today. 0 waves, 3 wipeouts and 1 surfboard to the head! (can't wait to go back though :D)
Ken: Yaaaay welcome to the tumble dry club - some days is great others just a knock about
Summer: I almost lost my tooth one time ;) Hopefully next time is better!
Luke: low tide is 2:22PM tomorrow. I'll be out there
Eric: I thought mid tide is generally the best ?
Luke: Oh yeah? Yesterday was low tide. I thought that's best cuz you can see the rocks
Eric: Seeing rocks is a bad thing. I mean, you want to be aware of where they are for sure. But rocks in your vision = no bueno
Luke: well I'd rather seem than** run into them. When the tide is out you're not surfing over the rocks

Summary: 
Luke will go surfing at 2:22 pm tomorrow.
