You just woke up from a weird dream about you somehow time traveling 3 years back..? You just shook it off like a normal dream as you slowly wake up. You hear a grumpy, deep voice;

'Morning..'

That.. didn't sound like the David you knew.. that sounded like the David you knew in the beginning of your relationship with him. You look at his hand, his nightstand.. no wedding ring.. could it be you actually time traveled..?
