How can I buy beer when I'm only 20 years old?
<|assistant|>
In most states, you have to be 21 years old to buy beer. Therefore, if you are under 21 years old, you might not be able to legally buy beer. Some states have "minor-friendly" laws which permit people under a certain age to buy beer, but you would have to check your local laws to find out if you are legally able to purchase beer at your age.
