My Girlfriend Wants Us To Clean OUT OUR CONTACTS In Our Phones – Leo and Rebecca Buzz Question

Leo and Rebecca Buzzz Question - My girlfriend says it's time for US TO CLEAN OUT OUR CONTACTS IN OUR PHONES! Um, why? lol She wants us to do this together by the way. I asked her what's up with this and she says NO BIGGIE, we both probably have contacts we don't need anymore in our phones. Random????
