'I point at the stars and the sky ripples.'
I would disrespect people who feel lonely by calling myself lonely - I have a handful of very close friends and am in a relationship. I don't find it easy to connect to other people in meaningful way. What needs to happen is both persons being in a spontaneous state, and that's a rare thing to find because at least one person always has somewhere to go or something to do, or is scared of something or is too attached to something, preventing the two people from enjoying the present moment.
One more word about 'science and atheism': I'm put on notice every time someone mentions those two as axioms to follow. Atheism means to me disregarding spirituality at all costs, and considering only scientific facts means invalidating personal experiences of themselves and people around them.
'A; Today I went X and saw Y and felt Z'
'B; it is scientifically proven when you X you feel Z but it doesn't mean you Z1'
The reliance on facts puts the emotional part of the conversation aside in favour of logic and rationality and reduces the potential of building a connection.
But hey, I'm not an expert at building relationships in the first place, these are just my thoughts and personal experiences, compare them with your own and build your own framework.
But yes people can sometimes be annoying.
A number of atheists have felt that, and some have even established groups modeled on the social aspects of churches without the particular theistic views (e.g., Sunday Assembly.)
