Some days, they look really good to go out, and swimming. Some days, they look really good to drown, drown, drown. How do you know what day looks good for simple treading? How do you know which days look good for nice floating? Sometimes you just have to try the water first. To see if it feels choppy, and to check for undertow. However, if you like yourself you'll listen to your fellows. You'll listen to the people that have checked that water first. Avoid the undertow! Don't dive where it's shallow! Avoid the undertow and you might survive the day. It's better if you're just treading, than, you know, drowning. We want to see you later, so don't die in the meantime. So, perhaps, today, we could all go swimming. As long as we avoid the dangerous people go.
