If the universe is in a state of expansion, why is the Milky Way supposedly going to collide with Andromeda?

I’ve heard that most galaxies are moving away from each other, so why is Andromeda moving closer to us?
Is the Great Attractor a factor in this paradox?
BTW, this is NOT a homework question, so don’t go squealing to my mom about this! ;-(
