Am i wrong to be annoyed?

this is what happened

(information you might find useful: i no longer have a car so my parents offered to give me lifts to and from work)

I finished last night at 2130hrs and as i was about to phone home my mate said he'd bring me back so i took the offer to save my parents the hassel. I got home and no one was in, nor did they leave a note (which is quite odd for my family to do) i then waited 1 hour and tried to phone them and my mum didn't answer and dad's went to voicemail. I then waited until midnight and they hadn't come home. I went to bed leaving a note saying 'thanks for letting me know where you went, lucky i managed to get a lift home really! i was worried because you didn't leave a note. i have work at 8am and i will need a lift - chris'

this morning my mum said she doesn't appreciate that kind of note or behaviour and said i should mind my own business....upon arguing my case my dad said 'you're out of order, shut up' to which i replied 'i really don't think so, you're out of order and please don't tell me to shut up'

That conversation took place this morning at about 0745hrs. I haven't spoken to them since..

Also it's my birthday tomororw and i'm going to be stubborn enough to ruin the whole day to prove i'm right. I don't care what it takes......this is the right thing to do yeah?
