Writing Feedback / There are many types of friendships; Friendships Classification Paragraph [3]

The only instructions I received from my college professor was to write a 5 - 12 sentence classification paragraph on anything. ( Those are exactly his words!) I would appreciate anyone who can proof read or edit this paragraph.

Thank you.

There are many types of friendships; however they're not all the same. Firstly, work friendships only consist of conversations related to the job and no interaction after work hours. Gym friends are similar to work friends because there is no contact after visiting the gym as well. Also, with gym friends there no personal information about the people is shared. The conversations between gym friends are mainly about health and fitness. School friends are the friendships are interacted with the most. There is more personal information shared between school friends; although mainly the conversations consist of topics related to school assignments. School friends visit each other and interact after school hours and on the weekends. People seek different satisfactions through the various types of friendships.
