Smile
Trisha has always smiled. When she was younger it was so very difficult, after her father died and her mother and she were left all alone with no money at all, but there was no use crying, and so she smiled. After she met Hohenheim the smiles came so much easier, so much easier than they had ever done before, and she couldn't help smiling when Ed was born and Al followed him.
And then Hohenheim left, and the smiles began harder to find again. But it's for the boys, and so Trisha smiles.
After all, there's no use crying.
