I'm 39 weeks and I live with my boyfriend's family....his mom feels that I should let her know where I'm going and what I'm doing if I leave the house....I do out of respect but I'm 24 years old and I know what to do if there is an emergency....I don't like her jumping down my throat like I'm a child if I decide to go do something elsewhere.
