well, cecile. it does sure a headache but with practice with other people, and making many exercises you will be good. you must know that even the french people don't know the "conjugaison" of all the verbs. you have not to offence your self on larning. just an hour or tow are sufficient. you have to see dictionnary about that. and if you need any help, i will be here for you; ok. bye and good luck.
