#7 Friendship
A term created by Homo Sapiens that lasts around 5-50* years which can be replaced with other versions easily.
Maintaining a lifelong friendship program is not easy at all. One can upgrade or downgrade the current versions or directly delete them by force. Some versions might leave bugs which cannot be deleted easily, so it is important to completely format the brain.
Special collaboration work with brilliant artist and dear friend George Boya.
*A 2009 Dutch study found that a large majority of friendships only last about 7 years.
