Sorry, but I must submit you to some bad poetry (if you bother to continue reading...)
I am not the friendliest person (it has something to do with being introverted and choosy about people with which I associate). Thinking about the friends I have and those that I have known, I composed the below dodgy poem a few years ago. I recall learning about the rules of poetry in school, but have forgotten everything. Some of the lines rhyme...sort of. It's the message that is important. Believe it or not, this was written before anyone had thought of Facebook or social media. Perhaps, the sentiments are more apt than ever...
Some friends you keep forever;
Some friends you keep for a day;
Some friends are there when you need them;
Some friends just look the other way.
Some are friends when they need you;
Some are friends for no reason at all;
Some are friends ‘cause you fit together;
Some are friends at you beck and call.
Some friends may simply come and go;
But, a true friend is pleasant to have around
Some friends are not there when you need them;
But, a true friend will never let you down.
