Time is indeed valuable. The more you mature the more you start to think if it's worth giving some people a bit of your time. I observe around me a lot of individuals who free their time to spend it with others while some never have time. I think it shows a different kind of standards when people spend their free time with whoever passes by versus the people who actually make time for you. It's quite a big difference of nuance.

For me personally, I appreciate when I know that someone is giving me quality time when they have important issues pressuring them. On the opposite, I have known people who "are so busy" doing nothing that slacking, but never "have time". I think we both know what kind of people we would pick to have around.
