Adults throwing tantrums
I see this almost once a day now. An adult throws a fit over something small. They drop something, they scream and shed tears. The store runs out of an item they wanted, they scream and cry. The person they just met won't go on a date with them, they scream and cry. Sometimes they have kid with them and their kids get embarrassed and tell their parent to stop it. Why can't they just shrug things off and get on with their day?
