I don't usually talk about age, but I am a year younger than you are, and I don't run into much trouble, I've noticed just making enough communication and using a formal greeting (odd) sometimes helps. The problem is people sometimes link age and skill, and sometimes that is a good way to judge skill, I'll admit when I run into kids in the trials I facepalm and consider finding another group. Some say I'm the best scrub ever (for acknowledging being a scrub) Just use your vocabulary, it sounds odd, but if you have a college level lexile score you probably know some massive words for your age, I've been called well spoken, and that instills a little respect, if not much. They key thing to surviving as a false squeaker is respect, just git gud, get them to like you, and you are good for the raid!
