its an easy answer, they dont, but as one thing started either by a visio of something or a lie, we all came from ages where religion was inculcated by families ever since childhood believe what u want, the easy thing is that there is no higher power or anything like that
hard to say, every person is different why dont you do stuff, like why dont you, hug him more, hold his hand, to mke him know that u want him to be close, kiss him, that kinda stuff
i dont give a fuck what people think about me, neither should others, if u stop caryin about others thoughts u will stop worring about insignificant shits
