Amusement park fun

I get ready for our amusement/water park adventure. Arrive at sister's house. Change of plans, they forgot about an appointment so I'm taking the kids alone (brother-in-law was planned to come and then leave for work). Issue, my niece's diabetic insulin shot needs to be done at lunchtime, so how do we do this. After appointment, the parents will arrive at McD's across the street to give shot. Ok. Explain to kids water park first, lunch, then amusement park, and home for dinner/supper. Get to water park. Ask kids who from past experience cry over hot cement if they need aqua socks or can handle walking barefoot. Nephew wants aqua socks. While in shop we get a beach towel for niece who grabbed a bath towel and that will not cover those beach chairs. Get in the pools and find out nephew is too short for the waterslide he insists on riding. On top of that, I grabbed the wrong inner tube for the slide so get scolded by lifeguards (sorry it's my first time here) and have to walk back down. We did get on one slide he was tall enough to ride and it knocked my sunglasses off, and water went up my nose. Have to leave for lunch and kids have to pout. Get to McD's and sister is upset about the beach towel when niece should have grabbed a beach towel, the aqua socks nephew didn't need, and the extra snack I got them when she gave me a snack to give them (which I did and they were still hungry). Plus niece lied about the pretzel I shared with her when they checked her blood sugar. Have lunch. When getting ready to do the amusement park, nephew hollers at me sitting in a bathroom stall realizing my period just started to demand I open the trunk so he can change clothes. I explain he can wait. Walking to the car, he informs me I should keep the trunk open all the time for him and I'm going do what he tells me to do. I give him the standard "Who do you think you are speaking to" scolding. I am the one with the keys, I drive the car, and he speaks to me like that again I will forget the amusement park and drive straight home. Didn't get anymore dispectful talk the rest of the day. Gave niece same warning. Any crying, whining, pouting, or dispectful talk and we go home. And yes, they are still small enough for me to carry them out. No problems at amusement park, we had a great time. Got some fish food and nephew had to forcefully grab nearly knocking the food out of my hand. I explain this is not a popcorn bowl so he can take only a few pieces at a time. Then had to leave. Last ride made the employee mad getting off too soon. Sorry the ride quit moving and we weren't the only ones getting out. Chat with my sister while they shucked corn cobs for supper/dinner. Then home. Then noticed my bright red sunburn while washing my swimsuit and short I bled over. No restroom I went into had any santiary napkin dispensers. Cats are so happy to see me.
