Attends the same event as you but drives themselves, does not save or invite you to stand in line with them, is seated at the table next to you buy does not sit by you or pay your bill. Leaves first and does not walk you to your car or make sure you get home safe. Then at home is awake and on their phone but does not acknowledge you. Then rolls over and goes to bed.
Leave. Me.
Please for the love of God.
