A friend is not a spare tyre that you pull out when you feel life has gone flat. Friend is the steering wheel who helps you to turn your life in the right path.
Never abandon old friends. They are hard to replace. A friendship is like wine: it gets better as it grows older just like us... I get better, u get older.
