Swimming Pools

Alright parents, this is a little rant here. I'm a lifeguard for the city I live in, I work at two different pools, have been for almost 4 years. In that time, I have dealt with thousands of kids and adults on any given day. The way public pools work is that there are lifeguards placed in strategic places to get full coverage of the pool at all times to watch for any safety risks or hazards. We aren't babysitters. We aren't there to watch your 7 year old while oh go work out. We aren't there to watch your 3 year old toddle around in the kiddie pool while you take selfies in the deck chair with your friends. We aren't there to make sure your little guys, or older guys, don't go too far and get lost, or venture into the deep end. Most of the time, we don't even know which kid is yours. But we see you, and we know you. And when your 18month old, that you should be in the water with at all times, toddles out too far and tips over, I can only get there so fast when I'm on the other end of the pool, answering some totally irrelevant question your disrespectful 8 year old won't stop asking me. Sometimes, it's only me watching the pool, and when there are 10 kids, plus lap swimmers, stretched out across the pool, for me to survey and supervise, I can't always see your kid in time. I do my best, I try to stay alert, I try to scan thoroughly and effectively, I try to count every person coming and going so I know how many are in the water at any moment. But sometimes, I just want to give my mind a rest on the 18 month old and make the mistake of assuming you, his parent, is watching. And sometmes, I'm wrong in my assumption. And sometimes the kid tips over. 
Listen parents, I know you're tired, I know kids are a lot of work, and I know you bring them to the pool to let them loose and get a few minutes to breathe and relax and socialize. I totally get that. But pools are dangerous. In a split second, your turn your head for a minute, and a kid falls under water. It takes only a few minutes to drown, and even if resuscitation starts quickly, brain damage from lack of oxygen getting to the brain can occur in just those few minutes the child, or adult, is under water. So even if we react in time to revive your child, they could be permanently brain damaged. And especially in a crowded pool, we don't always see a submerged child in time. I have deal with many emergencies, some very serious, some just a simple water rescue to help a kid in over his head. I don't want to deal with them, they're traumatic for all involved. I know accidents happen, but let's do our best to prevent them. Please, parents, I see you on your phone. I see your 5 year old dipping her hands in the deep end. All it takes is for her to lean too far over. Please, don't make me have to go through the guilt if I can't get there in time. Don't make yourself have to live with that. Don't make your child go through the potential trauma.
