You can not instantly assume one is taken just cuz of flowers. If a man was on her arm now, thats another story. Maybe as the Lahrell stated she was carrying it for a friend at the hospital, or maybe her mom or someone close, or maybe even someone gave them to her that is admiring her just like you. Now, the possibility of her having a boyfriend is still there, but just assuming one possibility off something as simple as this could be avoided by thinking outside the box. It doesnt hurt to be friendly and start a casual conversation about something. Just think of something to strike up a casual conversation that has nothing to do with you liking her.
