My mother

still manages to school us:

mama: i said, “that’s just not commonsensical” and my student was like, “what’s commonsensical.” give me a break.
my sister: …what’s commonsensical?
mama: are you joking? you don’t know what commonsensical means?
my sister: that’s not a word.
mama: wanna bet?
my sister: it can’t be a word!
mama: *points to dictionary*
