Curtis was just in the tub yelling:

"I think I got all the sand out, ya know? I dunked my head under the water three times to get out more sand. You know? Is there still sand on my head?

He's switched to singing "Born This Way", as he does. I took Curtis to the beach today for some boogie boarding and the waves were pretty decent. Maybe a little too high add to that an undertow from a retreating tide and I was wondering how successful this boogie boarding session would be. But there was no turning back once the shirts are off.
The best times with Curtis are almost always when you are one on one with him. That's just the way it is. When he's socializing with kids, you're hoping it goes well but expecting the worst and when there's more than one adult around, Curtis is unpredictable. Something about more than one adult interacting with him at a time can set him off to "rascal behavior". A lot of the rewarding times are with many people around but the one on one is the fun stuff. He feels much more loose and at ease.
For the most part today, I would have Curtis lay on the board and half hold him and the board while he rode a wave. Other times he just wanted me to lift him over a wave and dodge them so he didn't get plowed over. But there were also the times where he wanted to be a big boy and take the waves on himself. 
Curtis would climb on the board and ride the wave in to shore, usually hanging on to the board the whole time. But he couldn't figure out when to use his arms to brace for the impact when the wave eventually drops him on shore. Most of the time he was face planting into shore and spitting sand. And in the undertow and he would face plant, then get a quick water drag down his face and it was sucked out towards low tide.  He would stand up, hair and face covered in sand and look for his board. Thankfully he was never hurt, didn't mind me laughing, and was not embarrassed by the face plants. He wouldn't even really get that he should be embarrassed by them. And he certainly didn't notice all the people smiling at him as he grabbed his board and came back out to try it again. He just kept at it and had a blast.
He took a beating by the shore despite my attempts to help but got out only when it was too cold. He was telling everyone the rest of the day what a great time he had while simultaneously awaiting bath time to rid himself of the leftover sand.
