Responsibly using credit is an important skill in the modern world. Unless someone plans on paying cash for their cars, their home, and always having enough in savings for emergencies they will need credit. Having a credit card but not spending more than can be paid off and never being late with payments improves one's credit score which will help them every time they need credit. Even potential employers check applicant's credit scores now to determine if they are responsible so having a high score can help get a good job as well. Credit isn't something to be avoided entirely; it is something that should be managed.
I regret getting mine ten years ago. Its hard to pay off and get rid of once you have one. On the plus side its like having magic beans. It is not a decision to make on a whim.
I don't see why it should matter if htey got a credit card? Unless they have really bad credit, always unable to pay their bills or are without a job or any sort of income.
If they know how to handle the life of using a 'Credit Card' then let them be.
If that friend did'nt have enough money,i'd say be careful.
How would a friend getting a credit card affect me??
Nothing - it's their life.
