Disagree completely. All the most substantive experiences and memories of ones life happen within groups. Born alone die alone is reductive given each person only has fragments of information and insight individually, so we spend most our time together in some form
You are born out of another human but even they can never understand you fully, they can never experience you fully, they can never know you fully. The problems of parents and kids are all coming from that and are old as time. If even parents can't do that there is no chance with other people.
This is the trick of the universe, or a trade-off if you will: being completely alone also means being completely free in terms of internal experience. If you realise that - that is the greatest gift, if you are unaware it can feel like a curse.
I don't think so. Solipsism is not being sure about what exists outside of mind.
I'm saying that others can't understand you fully, not just the mind but whole combination of memory, emotions, experiences, etc. Therefore being alone is not different from being surrounded by other people, I'm not saying they don't exist or anything like that.
