It's a day when you'll be seeking greater depth from people. Some folks will rise to the occasion, while some might just not be able to reach the level of discourse you want. And that's okay: it's important for you to respect both possibilities. So if you have a strong urge to get philosophical with someone, stick to talking to one of your friends who you know is just as intellectually curious as you are. Your brain needs some stimulation and you know where to find it.
