UFO Sighting in Sugar Land, Texas on 2017-11-20 18:50:00 – Thin, cloudlike object

I was on my front patio with my fiancée and saw what first looked like a cloud hen a flock of birds. i then realized it was glowing and moving through the sky in what seemed more like a serpentine fashion. i pointed it out to her too and she said it kind of looked like a banner the way it was moving or like a snake. it flew out of view after about a minute.
