This is why I love my Twitter: it fulfills in me a primal urge to act out in class, in little bursts. Since having moved past school and into the working world, the class clowning urge was one I'd kept dormant. As it turns out, however, blurting out ridiculous things to a roomful of people offers every bit the dopamine jolt as an adult as it did as a kid, which turns out to be very therapeutic. In Twitter, there is a sense of ordered play. There is no judgement. You can talk to your neighbors, stand up and give a report on what you're doing, pass notes, make fart noises if that's your schtick (the highest form of comedy), or sit in the back, observing.
