Stripes of light

Today I visited my patents.
They live in an apartment for 44 years.
They live on the 5 th floor. 1 garage and then 4 apartments.
I have lived there my hole life before I moved to my own house with my later husband.
For a few years there was only a stairs to go with.
There has been placed a hole gallery on the back of the apartments together with 2 elevators.
Perfect because the people can stay there much longer and doesn't have to move because they cann't take the stairs fhysicaly.
Today I choose to take the elevator instead of the stairs and I saw these stripes of light.
The sun was shining (it is still very cold, brrrrrr, but I didn't complane ;-)) and that has to be captured on a blip.
