Yesterday I met a lady who was… odd, I think would be a good way to describe her. She had a funny three seconds staring habit. She stared at me for about three seconds before she said hello and three seconds after. She said something to be friendly and continued staring for about three seconds after that, and when it was time to say goodbye, she took three seconds longer than necessary to respond and I imagine she also stared at my retreating back for another three seconds before she carried on with her work.
