Cultural Tip
In France, leaving a party often involves 'le quart d'heure d'au revoir' (the fifteen-minute goodbye). Saying 'Faut que j'y aille' is the polite way to initiate this process without appearing rude or abrupt. Dropping the 'Il' at the beginning is very common in speech but should be avoided in formal writing.
