I first saw this artwork on Tumblr months ago and saved it on my laptop because I thought it was beautiful. I look at it and wish I thought of this first. Its simplicity and realism says a lot–this is how we look like when we cry. When we cry, blood rushes to our faces and gives off a pinkish reddish tint we call blush. Then the waterworks follow.
Now I have to deal with this blushing at erratic times of the day asking the same question.
