7 Day Black & White Challenge: Day 4!

I nominate @florian-glechner at my fourth day.
These are the rules to be taken into account:

• Seven black and white images that represent an aspect of your life.

• Present one image every day for seven days.

• No people.

• No explanation.

• Nominate someone every day, but anyone can join the fun.

• Use the tag - #sevendaybnwchallenge - as one of your five tags.
