由于父母的笑容而高兴,这话用最简短的句子该怎么说啊?

字面上

The smiles on my parents' faces brings me happiness.

只保留意思的话,

I echo my parents' happiness.

glad/happy because of parents' smile

The smiles of my parents make me happy.
这样更好些

I'm happy for the smile of my parents.

I'm happy for the smile of parents.
这样够简短不？呵呵^_^

smile of my parents is my happiness.
