One Paris' graphic street artists, PiTR 
met another street artist, Ella.

When asked how they met, PiTR said:

We met each other one autumn evening in 2007 in the streets of St Etienne, while pasting. Ella, who comes from the south of France, was pasting up her first drawings, and I asked her what she was doing and if she’d like to paste work with me. She said yes – now we have two children.
