Me, my husband and my kid who was 4 years old at the time were having dinner at around 7pm, on the apartment on a second floor. Our dining table is in front of a very large window facing west. It was already dark outside although a clear day. The kid asks suddenly "what are those giants there?" I see nothing outside the window. He goes: there are three giants there outside of our windows. I ask "where exactly?" He goes" they are standing right there, on the street!" (He points to a small alley that is visible from out window) I don't see anything that can resemble a person. I ask " how big are they?" He answers "they are there. Can't you see them? They are bigger than that house ." I ask for more description and he says they are white, have no mouth, and have a funny hat. He is now 5 and still remember the giants. I asked a couple of times in similar light/weather conditions to check whether it was a light effect but he has never seen them again either. sometimes he asks when will he see them again.
