Why do we share things with one another? Is it to change their mind? To impose our will? A bit of both?
Sharing is integral to the process of being known. Whether that is to share with the intention of aiding another, or merely as the very object of sharing is special to you. It is a process that adopts a level of vulnerability and is the extension of the proverbial olive branch. The simple act of sharing tells that 1) you are comfortable within your choices on a topic to project them publicly and 2) you trust the receiver to an extent to allow them to know a bit more about you.
The energetic exchange that ensues holds itself in constructing the identity of you within their mind, a mental map of sorts to which they use in their interactions with and about you. Legacy is then to be known. To leave this vessel knowing that some form of you exists in the minds of others and has been compiled within their actions unto others upon others ad Infinium. Then it is to be said that the feeling of loneliness is the feeling of the lack of being known. That in the same respect one can feel lonely amidst their closest relations posits that they feel less known than desired.
This is the responsibility of the sharer, for such a state can be due to their lack of vulnerability and their lack of trust in allowing their knowing of you. To the very extent that it is the responsibility of the sharer to place themselves amidst those for whom care to know them in the first place. If in any event that such vulnerability has transpired and the receiving party has done nothing with it, then accept that it is outside your control as to how they continue with that, and instead decide on whether they are to be kept as a relation. This can occur in the form of communication on the topic of sharing and as to how they do with such information. A reminder that there can be the quiet and actionless admirer for whom has the utmost love as to what you have shared.
Hasty assumptions have been the plights and downfall of many, ensure you act differently.
Use discernment and vulnerability.
