It's almost impossible to go your whole life without inevitably relying on someone, at some stage. Whether it be emotionally, financially or otherwise. Unfortunately, in life, you soon realise, that you can't always rely on people, even the people you feel you should be able to. I've had to learn this the hard way. But it's difficult being completely independent.
I think at some point, you have to find a healthy balance between standing on your own two feet & knowing that you have people who'll be there for you, when you trip & stumble. I also think it's important to be that support for those around you & to remember that, what you say as a passing comment, may be taken as firm action by someone else.
So it's always wise to mean what you say & say what you mean. Don't make empty promises, whether they're little or large. Always give with an open heart, be understanding & love unconditionally. At the end of the day, that's all anyone can really ask.
