So, do not be upset if someone ignores your advice then accepts it from somebody else. It is not that they don’t believe in you, but because they weren’t quite ready to hear it.
…and if it’s someone you love, perhaps they just weren’t able to hear the words from you at that time. We sometimes like to paint a perfect picture for people we care about, and can’t allow anything to disrupt that – even if it happens to be sage advice.
Don’t be upset – just be happy they were able to hear what they needed from SOMEONE. It doesn’t always have to be you, and it doesn’t mean they love or respect you any the less.
