should be 'Jackie'
vous devriez être
You should say " Hey, I don't really like the idea. So, maybe we should wait a little.

J'ai appris le français (my french isn't that great but this should be it)
If someone sneezes, and you want to say bless you in french, you should say salut.
If you say it to someone you should use : "Étudiestes maths"
clapet d'échappement At least that should be it...
"Quel dommage" should work.
Lady in French is 'dame'. Son in French is 'fils'. To say 'the lady and her son' you should say 'la dame et son fils'.
