2. You are thinking about going to the movies with older kids you really don't know.
3. You aren't sure if you should cut your hair.

Using the DECIDE process would allow you to thoroughly evaluate the situation, weigh the potential risks, and make an informed decision.

Similarly, in scenario 3, deciding whether to cut your hair may seem like a minor decision, but it could have long-term consequences on your appearance. By utilizing the DECIDE process, you can carefully consider the potential outcomes, consult with others if needed, and ultimately make a decision that aligns with your personal preferences and goals.
