Hi gyal,
First I have a request for you :) ... You need to provide a meaningful line for the subject (your essay topic). This also helps you to attract more comments for your essay.
Friend isa most important companion in your life.
.... yes indeed :)
All friends have different characteristics, some are very frank and some are very intelligent.
.... Better you keep this idea in a more broader sense;
People are very different in their characteristics and friends are no exception. Some are very intelligent and some are not. Some love humor while some are moody. You can rely on some friends, but not on every friend.So in my point of view, reliable friend is most important to me.
For me, reliability is the most important characteristic that I look for in my friend.Firstly, friend must be reliable. They must trust each other, from that we gain respect and love. Whether your friend is poor or rich and educated or uneducated. We should respect your friend and give lots of love. Be companion your friend forever, whether they are in sorrow or enjoy life.
... give a more specific example to support this reason. Talk about a situation where the friendship has got strained because your friend was not reliable.
