Don't just show, share
Consider the following:
"Check out this expansive new car I bought!"
This is showing. The person doing the showing might get a kick from generating envy or jealousy from people who care too much for their own good; and risks looking silly to people who have seen it before or just simply don't care.
Now consider when you share instead:
"I just bought a new car, want to go on a road trip together?"
