Sometimes, the smallest things can make or break your day. A hangnail that hangs loose for an entire day until you come back home. An ignorant driver causing a jam and making you late to work. Or a plane passenger putting up their bare feet next to your armrest for a 10-hour flight.
While the first two were hypotheticals, that last one actually comes from this list of slight annoyances people have captured in photos. Bored Panda has another compilation from the blood pressure-raising community “Mildly Infuriating.” While none of these will probably make you pop a vein, they might still cause you to exclaim “Really?!” in exasperation.
