I think this second panel is sharing the common element of a list of at least 5 things we can do. It could be just like your poster of all text or a list of things we can do and images.

Here are a few items -
Share an umbrella
pay the toll for the car behind you
let someone use your cell phone
Put a shopping cart away for someone
Help change a tire
Offer to lend a hand
