How old am I

So this morning I wake up to an email from J saying that he will be able to MSN chat after while so I sign in and turn up the volume to my laptop so I can hear when he signs in. He comes online and we chat for a good while. He says that he needs to go do something and then he is going to bed. I make plans to go shopping with a friend. While I am on my outing I get several phone calls and text messages saying that he is on and waiting on me. I get one phone call and I am not going to name names just incase don't want to cause problems. So she calls and says J is waiting for me and I tell her that I am not near a computer would she please let him know and that I am sorry. She proceeds to ream me out because I am not home and demand to know where I am and who I am with. First off I am an adult, I don't have to explain my whereabouts to anybody. Second of all, she is not my keeper if I want to go shopping with a female friend I should be allowed to. I hate I missed a chance to talk to my husband, but I do not want to be that wife that can't leave the hoouse for fear of missing my husband being online. I would be miserable. So what gives this person the right to ask about my whereabouts. I live with my parents for the time being and the only thing they ask of me is if I am going to be out late to let them know, I don't have to tell them where I am going or where I have been. I don't have to tell my husband what I am doing if I don't want to.

So in conclusion of my rant I want to reitterate that I am an adult, if I want to have a girl's day I can, if I miss a chance to talk to my husband I hate it but for my own sanity I cannot be tied to my computer 24/7.
