I would do it
Si tu ne le fais pas, je le ferais.
If you don't do it, I will.
I would do it myself.
I would do it.
Of course I would.
Parce que j'ai dit que je le ferais.
Because I said I would.
Si je pouvais quelque chose, tu crois pas que je le ferais ?
If I could do something, don't you think I would?
