Wise words. I think that unconditionality and genuine care and interest in how someone is going is often misinterpreted. I know in my life there are several people who I only ever hear from when they want something and I think, because that so common in society, some people immediately question what you want when you try to check in on them.
And yes, it is definitely better to try and focus energy where it is needed, appreciated and is reciprocated.
