In French, you don't really say ''I miss you.''
You say ''Tu me manques.'', which is closer to ''you are missing from me.''
I love that. ''You are missing from me.''
You are a part of me, you are essential to my being.
You are like a limb, or an organ, or blood.
I can't function without you.

Celle là est un peu pour toi.
Tu te reconnaîtra seul.
