My aunt's two sons are:
mes fils
mes cousines
mes veveux
mes cousins

Option B. My cousinsAunt means your mother's or father's sister.When children have same mom they are brother sister but when they have different parents and one of their parents are related they are termed as cousins.

Not sure this is related to french.i'm not a relationship master, but it might be that your crush is trying to "flirt" with you and try to get your attention, because he has no other way to show it. or, he just simply might not like you.

Dog
in french = chien
