confused on the concept of friendship

i was just wondering if it is really in my nature to be "contrabida" to my friends. last saturday, thors and i gave a gentle reminder to one of our barkada to be considerate in her actions. we just thought that she went out of her way that night just to have fun. we were really worried about her bringing her car to a gimik in makati knowing she hasn't mastered the 'art of driving' in edsa yet (she never actually tried driving in edsa). we picked her up in makati and i drove her car going home. i don't know if thors and i went overboard by telling her what we felt that night. i really didn't want her to think that we were beginning to be her mother telling her things we knew she didn't want to hear. i just wanted her to realize that there may be times that we may not be there to give our hand because we also have our own lives (wherein it may be possible that she may not get any help) so i wanted her to consider thinking about her actions (not to be uber confident that we are ALWAYS there to fix the mess a.k.a 'lagi kaming nandyan para sumalo) i don't know if i am just being so 'righteous' about everything or if she was really at fault. i don't know if i should have just helped and said nothing or i did the right thing. i don't know if i should have not help that night for her to realize some things that by now she should have known. that night, i wondered if she'd ever ask for my help regarding anything again. if she wouldn't i may feel that i made the biggest mistake in my friendship chapter. nevertheless, i still want her to know that i'd still be here for her no matter what.

i've had quite a number of 'colorful' episodes with friends.. i'm not sure if i'm a bad friend or if i am just a friend who cares.. i'm not sure if i am a person who loves to exagerate things or just sees beforehand the possible consequences of an action.. i'm not sure if i am the "contrabida" or the "supporting actress"...i wonder, is there a limit when it comes to understanding your friends? is it really a bad thing to worry for the people who are special to you because worrying for someone always end up in a fight? is saying hurtful but true things to a friend going overboard? does a friend just need to be there to help and not to guide since guidance is given by the parents and not friends? when is that point when one can give up on a friend? what in the first place are the resposnibilities of a friend? is there such as thing as a perfect friend for anyone? damn.. right now, im not sure of anything... i don't know anything regarding the concept of friendship.. but i'm sure of one thing, i love my friends and i'd do anything for them as long as i can..
