Why do some bounce back more quickly than others?

Why do some people bounce back more quickly than compared to other people when they lose someone special in their life?  I don't get it at all.  Some people after three months have a better attitude than compared to me.  Losing Smokey tore out my heart.  I am still mourning his loss and it is getting better in little incriments.  Am I dwelling too much on what I loss?  I just don't get it at all. 
Men are pigs.  When I was out with a bunch of people on Friday, Smokey's birthdate - April 30th, one of my friends Carol got groped by one of my brother's friends Blair.  I said to Carol you should have said something to Blair.  She said she could have misunderstood it and would forgive him this time but if he tries it again she will say something.  I would have said something right away.  Carol has a boyfriend.  I always thought of Blair as being nice.  I could be wrong.  I told Don and said Carol would forgive Blair this time but if there is a next time she will speak up.  Don said Carol was wearing a very sexy top and all the men were looking at her.  Carol is not a small women and does have ample everything.  The guys don't notice the everything just the cleavage.  It is the difference between men and women.  Need I reiterate that men are pigs.  I am speaking from a stricly female point of view.  I was wearing a cleavage showing red t-shirt summer top earlier in the day.  I did change to another red top with longs sleeves as the day was getting cooler out and it did not show any cleavage.  It makes me wonder about having to cover up more not to get unwarranted glances from men.  Even my Smokey always admired my "cleavage."  Actually the real reason I changed was when my brother Don was over earlier he kept looking at my cleavage and he was my brother.  I felt so self conscious about it that I changed into a top that showed little cleavage.  Men are pigs even my brother.  Ugh!
