Terrible 2s

Jack is a pretty good 2 year old. He's only had a few full-on tantrums but he does get whiny and bratty when he wants something and we won't give it to him. So here's the question: Can adults have tantrums too? What if there's something that I really want but I can't have it? Can I stomp my feet and swing my arms and scream and whine? I really wish I could. It might make me feel better.
