How to make happy?

I need some suggestions from all of your sides and I am hopeful that you people will like to help me. Actually, My one friend is very sad in these days due to something bad which occurred in her life a few days back. Noe, she is suffering really a bad situation and forget to smile. I want to make her happy like before. What can I do in this regard?



I am sure day trip to yosemite from san francisco will be amazing for me.
