You can hold open doors, push up their chairs, compliment, help them pick up stuff they drop, encourage them, help them through hard times, hug them, help them with work
I think that this is a very good opening paragraph. I can clearly tell exactly what your writing piece will be about, and it definitely hooks me in as a reader... GOOD JOB!
