Do you have a true friend, other than family or spouse, that has proved his/her loyalty in real life situations? One that would risk his/her life or well being to help you, one that would do good things for you without expecting your gratitude or returning the favor?
So it's not a true friend unless that friend does something like this?
Either way, yes, I do believe in friendship,all of those things has happened for me, where they've showed loyalty, risked their wellbeing to help me or prevent me from being hurt and do things without asking for anything in return. I've done the same for them.
Sadly because of how antisocial I've grown from a variety of reasons we've really glided apart from one another.
Still, if I am to get out of my rut and be social again our friendship flame wout ignite like *snaps fingers* that.
That has also happened before. So I know that if I ever need them then they will be there for me.
So yes, I do believe in friendship, even though I don't think a friend needs to show those things you listed in this quote in order to be a "true friend".
As to when I get older, who knows, I'll likely die before I hit my 30's so I don't care.
