Welp think about it this way
if you lost a friend, I guess they weren't really your friend. Y'know?
Doesn't necessarily mean that
There are several factors that can ruin a friendship. A fight, them or you moving away, etc. Sometimes your relationship with people just slowly diminish over time, and there's not much you can do about it.
I agree in certain aspects. Relationships certainly are a learning experience and take much learning in order to work properly, however we define "love" much differently, as do most people, and it varies as per the situation as well.
Well, love is an emotion. And really, there's no way to describe an emotion. That's just my way of describing somebody when they're in the state of being
in love. :p
