You asked her a question, “Is everything alright?”
Her eyes watered and her lips quivered as she started to say, “N..” But then she saw how your lips thinned, saw how your head tilted to one side, facing the other direction. She saw how your eyes darted to the left, then to the right and your feet impatiently tapping ready to run off as soon as deemed appropriate. She saw how you crossed, then uncrossed your arms and your body language saying you want to go anywhere else but there.
You didn’t hear but she sighed sadly, swallowed saliva and with a smile pasted on her lips, said “Yes. I’m fine, just tired.”
