Epilogue:

Rhea told me that there are times when Sam will choose to do something, and even though she knows he's making the wrong choice, she will let him. He once ordered a mojito at a neighborhood bar, and even though she knew that a bar like that probably wasn't the type of place to ask for a mojito, she let him order it. When the waitress came back and told him that they didn't even have the ingredients on hand to make a mojito, Sam ordered a Long Island Iced Tea instead. And even though a Long Island Iced Tea was way too strong for someone like Sam, who barely has any tolerance at all for alcohol, she let him have it. She said it's better to choose her battles.

So sometimes you let it be.
