* When it feels like it: This implies that something is done reluctantly or only when the person is in the mood. For example, "Voy a hacer la tarea cuando se anime" means "I'll do my homework when I feel like it."
* When the time is right: This suggests that something will be done eventually, but not necessarily immediately. For example, "Cuando se anime, te invito a cenar" means "I'll invite you to dinner when the time is right."
