Lost..

I was visiting my sister for the holidays. While on board a bus, there was this couple sitting across me…
They must be newly married since they both looked pretty young and very much in love.
How do I know this (no I wasn’t staring at them!) well thru’ out the journey, they were both singing songs and quite loudly too… While she was a little abashed and looking out of the window while humming, he was constantly looking at her and singing…
Truly lost in love I’d say…
