What a surprise! A few weeks ago, I found myself no longer getting furious when happy families get into my sight. 
In fact, I found such scenes heartwarming. I used to avoid going to AEON or other places that attract "proper" looking people, such as young families with small children and people with friends,  because I felt an indescribable anger and urge to disturb their seemingly peaceful lives.
But now I can see them without negative emotion, or  even feel something warm from them. 
Does this mean that I have matured enough to celebrate other people's happiness? or that I got too old to keep the energy to get mad at the happiness of complete strangers?
