envious?

i was at lunch in a fancy & quiet cozy spot downtown with a friend when the topic popped up.

She was saying 'i opened a friends fb page earlier,and reading her status 'mom to be' doesnt make me want to congratulate her. Instead i just closed the page.

I can relate, knowing that she and her husband are trying to get pregnant for sometimes now. But i cant help myself but wonder 'is it true that we can only be happy for others if we feel enough and above?'.. Can we trully embrace their happiness when it or something better has NOT happened to us?.. How about the term that each of us has our own portion and timing?

Is this feeling is what known as envious? Or it just something so human that we all have in our heart?

I know i have it in me sometimes...
