Last night I went over and his mom wasn't there but it usually isn't a big deal because we've been left alone plenty prior to this.  but she knocked on his room door and he stupidly replies "I'm sleeping" and so I'm like " I have to leave!! wyd!!" and he's like she's going to bed it doesn't matter. when I thought he'd just tell her that I was there! instead of lying. so long story short she saw me leaving and told him that he needs to be honest with her. however, I'm super embarrassed and don't know what to do!
