sorry and thank you

sometimes, we don't know.
or I should say when the time we should know, we always don't know.
how to say thank you to somebody that you really mean it?
well, we will say "thank you", may be in many times.
or may be we will give that people a gift, to thank him or her.
but may be and may be
what we need to do is just do what we suppose to do.
may be they do many things just to make you happy.
Then, you just need to be happy, i think this is a big and meaningful gift for them already.
And may be this is the most work way to say THANK YOU.

How about to apologize?
is it same with thank you?
I can only say it depend on people.
Sometimes, it can be same like the way saying thank you.
you don't need to talk to much but prove or apologize through your action.
you regret about something, then do it the right way.
People may be will forgive you.
Sometimes, different situation.
Whatever you do, you couldn't be forgiven. What should you do?
May be that people involve only need a few simply words, that's : I am sorry, please forgive me.
But we never know. Never know what the people want.
When you realize, you will feel Oh My God!
But sometimes, that few words is the most difficult words to say.
That time, we should think : Is this friend important to me, am I cherish this friendship?
If the answer is yes, then please go ahead to him or her and say: I am sorry.
