yes. i also think it's rude to get up and change your alarm to fifteen to twenty minutes later more than once. my roommate does this all. the. time. especially on saturdays. and it's the most annoying thing in the world. my alarm is vibrating so it only wakes me up and i get up for when i set it to go off. if you aren't going to wake up until 11am, don't set your alarm for 8 and keep changing it. god.
