let's talk!

i have some questions but i am not sure if there's anyone who'll be interested to bother their minds and will give  answers to these questions.

i don't know if you do or probably heard from anyone the phrase i'm just here for you but whenever you really need them you're not sure if they are really there or they meant what they said?

how true is the old adage below?

"Laugh and the world laughs with you; weep and you weep alone."

i'm asking these questions because in my life, whoever will show kindness to me is already a friend, regardless if they are REAL/TRUE or NOT but there are some times i also feel so alone even if there are a lot of people around me.

so... in your own opinion, how do you define the word FRIEND?  how do you differentiate a REAL from a TRUE friend or vise-versa? in your life, what are the roles of a FRIEND and is there any limitations?

i hope you won't consider these questions as vague. i just want to hear some other ideas too.
