Study French Again?

During my summer holidays I met the little daughters of one of my father's French cousines cousins.

It was funny fun to play with Ornella (1 year old), but I couldn't interact with Chiara (4 years old) because I couldn't speak with her.

Back home I looked for my old books of French old french books. I studied it in middle school (20 years ago!).

I can understand almost well written texts almost understand written text well (French is cognate language to Italian) but I can't talk because I remember only few words. I've watched some video on youtube (by Cyprien and Norman) and I can understand enough to laugh at their puns if I know the topic.

I'd like to improve this language that I've underrated.
