Second "little" brother outing

Today I had my second little brother hang out. We went to Balboa Park. We first started with feeding the ducks which he really liked. Second was bike riding and since my bike tires were flat I had to roller blade with some really old roller blades. He was a beginner when it came to biking so I tried to help him as much as I could without killing myself being on roller blades. He hit a fence once but was doing pretty good until we hit a slight hill. He couldn't slow down so I tried to jump and help but releazed that I was no help since I was rolling backwards and into some bushes. He managed to stay up and made it down the hill but I did some great balancing tumbling act and managed to tweak my back a bit. After that I was done roller blading. We decided to walk around the park a little and he saw that there were paddle boats and wanted to ride. We had to walk all the way around the lake to get to them. While we did that we played some kick ball. We get to the paddle boat office and he says he wants to do a full hour. I tell him that we can do a half hour and if he want's to continue then we can extend it. Luckily I did that, because no more then ten minutes paddling around the lake he tells me that he is not feeling well and wants to go back. We paddle back and I tell him that it's time for lunch so we start the long walk back to the jeep. As we are walking back he tells me that he has to go to the bathroom, I tell him "oh that's fine thereb are bathrooms here" well come to find out that my "little" doesn't like to go to the bathroom #2 anywhere but home and he had to go for the past two hours and if he could just go home instead of lunch. So I took him home and only spent about 2 1/2 hours with him. The outing started out fun but ended abrubtly. Our next outing is going to be a movie outing.
