At home I always sleep naked my sister or mom generally enter my room most mornings to be told "GTFO I'M IN BED!" and once my sister was like "GTFO of bed lazy ass" I was like "when you GTFO" she refused so I simply said "I'm naked...wanna see?" before she left. When in other peoples I sleep in boxors only or if they have small kids/moms who might enter then T-shirts.
