know my blood type

I tried to find out my blood type this week, but apparently nobody knows my blood type. I went to the doctor for something else and thought I’d ask him about my blood type as well. He told me that when your blood is tested they don’t check your blood type, unless you or a doctor specifically asked for it. So there was nothing in my file. Kind of weird, since it might be important to know your blood type.
I thought this goal would be easy, but it might be a while before I can cross it off. I don’t expect to need a blood test any time soon.

I’m just wondering howcome I don’t know this. I’ve had bloodtests, so my docter probably knows my bloodtype. Guess I should just call.
