The best way to say "good bye" is to say "keeping growing and going.... My best wishes are with you"
The best way to get along with a person for long is never open up with him and share very little to keep the relationship continued......
The best way to calm down your undercurrent is chat with the person because of which the trauma of undercurrents is increased either by out-bursting the anger or by listening him/her. Alternatively, you can divert your emotions towards your hobby or near / dear friends so that the peace of mind can avoid any further damage to the other relationships...
If you are in love.... My Advise is not to be in love...........but to keep going with the happenings in life, though love is also a part of intake that the nature wants you to have hence cannot be avoided completely
If Love happens then....
=>Always let your love partner not know your true feelings for him/her.... this gives you more time to understand and say "no" comfortably if your mind changes....
=>Let him/her wait for you or your response...let him/her keep guessing about what you ..... Let him/her run to look for you.....
=>Always go with friends/sister/mother/father to meet him/her so that there is not much to say between the two and meeting ends with "see you tomorrow" note... and understand what he feels thereafter....
=> Make him/her come on your knees either because of love or because has been left with no choice...but if coming on knees due to no choice then remember there is very little that you can do to take it a long way....which means plan a short term goal only with him and try your luck when he/she realizes the love in you for her/him.
Today the best thing I can do is stop writing because many of you might have been bored of going through such advises..... But I have to keep going as everything cannot be done for enjoyment and someday you all will also realize it, as life is a cyclic change that begins with childishness then move on towards maturity and then ends with childishness packed with maturity(oldagers), though the reflection of either of it or both can be seen at many times... It is because he is confused should he/she enjoy it like a child or should behave like a matured person and brain at that age is not capable of arriving at a conclusion.....scientifically..... but the truth is that before you die.... the nature wants its pure hearted child back ....................
