How could?

i've been living for just only my member of 5.
just parents and their kids.
without aunty, uncle, and grandparents.
i've been living for 20 years like that
how could i know about the togetherness and kindness from another?
i just living without caring of another people except of our 5 members.
how could i know?
how could i learn?
then i realize..
thats not just our..

im thinking,.
why i always had a bad perception about another people.
when i think about, i had no idea.
maybe theres a hole inside of me, called "ALONE"
