I often think on the premise of Friendship or Friends and just how it can be viewed as multiple things...
A friend can be a mere acquaintance that you have no problem with and even barely know, or someone you have dealings with in business or ideals that are mostly agreeable to both people and then of course there is the perhaps most popular view point two or more people who genuinely care about each other and look out for each other when they can,
Friends and Friendship....what decides the strength or characteristics of that bond is what the individuals feel is noteworthy or not
