My Dear "FRENEMY"..

FRENEMY. Dont get astonished to see the word. Its just FRIEND+ENEMY. I was going through a daily newspaper article and I fumbled upon this word. I smiled a little when I went through the material. While reading I could visualize some incidences and persons. Ok its human tendency and you can't blame me. I thought of getting closer into this matter.
I came across many people and personalities(I like to differentiate in this way). I havent thought that people may come into this category or I can say I havent felt people to be in this category. After reading the article I could visualize those moments which came to my mind instantly. The article was a good one , describing what a frenemy is ,where they are found and how to tackel them. But one question is, if i know that the person is a frenemy then why should i continue with him. The answer came to me from my conscience(as I am a grown up dude).
The thing is clear, 80% of people I come across daily are unknown to me.15% are people with whom i deal daily.3% people with whom i talk daily(talking and dealing are two aspects).1% people i share some lighter moments. rest 1% are called friends. you can see the number is meagre a fraction of people i deal daily. So what if i ignore this 1%. Simple answer I will be left lonely and will be left out of those crucial moments of life which i should share with real friends.
The reality is, everybody has this pattern. I know some of them will disagree and will make this 1% to 50-60%,but analyzing the scenario will definitely boil down their calculation to my level. whatever. So if this is the pattern, how could i differentiate a friend from a frenemy? tricky question but you can make it simple. lets take one example.
we are two friends.went to attend a carnival(summer type). we attended it and at the end we are given two new books,identical and new. But what my friend(now distinguished to other category) did is looked into his book, then into my book and suddenly exchanged it. I couldnt understand. Before i could understand anything he wrote his name on it. I asked him why he did this? he told that " this book is good but the book given to me is defective .". I prefrred to keep my silence. Many other occasions are there but i shouldnt disclose and this one is enough to make you visualize. You will say that its a simple thing. But simple things should be considered before they get into complex things. what i mean to say that intelligent people should understand the criticality of the situation and what could happen later.
what should i do now? never look into his face and abuse him beacause he tried to take advantage of friendship. the answer is a big NO. Remember i have told about the 1% of friends, a majority of the people are of this kind. If i take such foolish steps, I will be the loser. I continued but with caution. The levels of intimacy and closeness decreased to a greater level. But the big thing is 'I continued'.
I dont want to guide you what to do or what not to do, but only want to tell you my experience about the concerned matter. So its upto you how you recognize them and deal with them.
