Ok so this is what I posted, sort of:
Will you tell me about the first time you took your car to the shop for an oil change/check up/whatever? I'm going in half an hour and I'm really nervous. I know absolutely nothing about cars, I don't drive very often (I have trouble remembering which side is the gas tank opening is on, which makes for awkward situations at the gas station). I'm going because I'm hearing a suspicious dull clicking noise, and also for an oil change. Will they laugh at my incompetence and rip me off? =(
Are you aversive to getting help as I am? I feel really embarrassed/awkward about asking my amateur-car-mechanic friend for help, even though he's the nicest guy ever and is really willing to help me.
Please help me with my unreasonable anxieties!
[EDIT]
Thanks for the great advice, I love you guys. I'm off to the repair shop now, hope all goes well!
