Strange Request

I'm working on the premise that the op is either at school or recently left. And it's not going to do any harm to give it try.

You're right I know nothing about being a courier but do have experience looking for work placements for young people so thought I'd offer some general advice.

Will is right to tell it how it is, but I suppose there is respect due to the OP for at least asking. Sure, nomatter what the job or career, we all had to start somewhere and relied on others to cut us a bit of slack in terms of understanding what is involved?
