When you sell something it changes owners. People pay others for a material object they think will better their life. It can be a meaningless piece of junk, or something vital to survival. It could be something for business or pleasure. The key is money.
A pupil is one who learns. A pupil can be any age. As long as one is learning one is a pupil. I have been a pupil my entire life. Sometimes to teachers, coaches, and parents. But always to this profound world in which we live in. I am a student of the universe, and I will never learn all it has to teach.
