How about these for the list...

You get to register for classes in college with the seniors when you are a
lowly underclassman and get every class you always need.

People offer to carry your bags, boxes, etc. all the time (even though you
can do it yourself!)

You are offered a seat on a crowded bus.

Pets get out of your way as you are walking so you don't step over (well,
on) them!

You are naturally good at falling.
