I hate it when people touch my computer! in Rant

Seriously who the f*ck help themselves to the computer whenever the see one without even asking permission? Now because of him I have to do setting and password all my account, such troublesome! He make my life complicated!
So nightmare is my husband friend “J” the one who been leeching on us for food while my husband was studying is moving over to our town and start working with my husband.
He arrived 1 week ago and spent his weekend with us and leeching on the food I cooked! Not only that he stayed until 9p.m on Saturday and 8p.m on Sunday. And the whole Sunday afternoon he was hanging out with my husband (they went hiking - I’m heavily pregnant so I cannot go hiking with them). And come back around 6p.m and went straight to the living room where I place my iMAC.
I was watching Devious maid on my iMAC and went away to toilet, but then he help himself to my computer and started maneuver around it. I HATE IT because he did not ask permission and i am still log into my account. THIS IS INVASION OF PRIVACY. I don’t go around his house and started using his laptop. Why can’t a person understand the manners to ask before putting their hand’s on other people stuffs??????????
I seriously have problem with this friend manners. I can’t understand why people cannot be a bit humble and well behave, ask before touching other people stuff. That is extremely simple things to do. I forseen very soon “J” will start placing his “stuff” in over house too, just like last year… WTF.
Oh not to forget, very soon he will have the say to watch movie I have to watch while spending weekend movie time with my husband.. Seriously marriage sucks if I have to live with the friend too.!
I Hate it even more because now my husband will be spending all weekends with him (ya you might said he just arrived, but I know him since last year and he is a very needy person and enjoy overstaying.) Baby is coming soon, I just want my quality time with my husband. Last year my husband have no time with me, and now I have to give my husband away to the friend too?????? Yes you might think during weekdays I can spent time with my husband but he overtime so much and only come home real late. And when he do come home he spent more time on clash of clan than on me. I am just frustrated!
