Vera was preparing her morning hygiene as she dried off and put on a house dress with her fuzzy socks her landline phone started to ring. Vera answers the phone It has been a few days since her mother called her. Vera says I am glad you are doing better mother. How is Deon doing with that basketball career? Mom, Deon is also an honor roll student. Well, does your boy have a career path other than playing sports. Yes ma'am he will be doing a job as a business manager position making a good pay. How are your other children doing? Yes, all of my children are doing well Ma. All but Velma Jean didn't the doctor label her as being slow. Well, mom she has made some improvements. She has a tutor and she is no longer in that class which singled her out from the rest of her classmates. Vera's mother talked a few more minutes than Said her goodbyes and they ended the call.
Vera always looked at her mother side of the family as if being one sided and everyone did not accept their family due to expecting people to measure up too other people's expectations.

Why is Deon being looked at as only a career in sports?
