I know the one about embarrassment.
But I got over it. Had to 'cos I've needed a lot of help at times
It's actually very simple:
1. People *want* to help.
2. People *like* to help.
3. They are so busy enjoying helping you they haven't got the energy to think at the same time "Yeeeowww! Is she stoopid or what?!"

This goes for all of life, not just bike maintenance
