Women a sleep on bench

At Kendall Green station there are 2 benches
end to end. On Wednesday night when I got
there on the way home there was a young women
fast asleep on one of the benches. She was on her
back, her phone balanced on her stomach. She was lightly
snoring. I sat on the other bench next to her and
started to read a book while waiting for the train.
In a few minutes her phone rang and she woke up
with a start, grabbed her phone, and looked around her.
When she saw me she gave out a yelp, jumped to her
feet and dropped her phone.
She clutched her chest, took a deep breath and apologized
saying she gets spooked when people sneak up
on her.
The train came a few minutes later and she did not
get on.
