It often happens that when we know that something good is going to happen to us at a certain moment we don't stop thinking about it with anxiousness for that monent to arrive and as time goes by we tend to get impatient.
After more than a month without seeing my wife or daughter tomorrow finally come to where I am and I have so much emotion that I feel impatient.
I think it's instincts embodied in our genetic code that give us that feeling of well-being for something that we know is going to happen and that changes our mood even before it happens.
My daughter was 5 months old the last time I saw her, she was about to turn 6, tomorrow I will receive her with 7 months of age and now she says words like father, mother and makes gestures. I am sure that tomorrow God will fill my heart with joy as I meet my wife and daughter again.
