RSVP Friendships and BBB..!!!

I always like to have more friends. Enjoyed a lot with them. Recently i heard from a friend that his friend wanted to talk with him for several hours even during the exams through the cell phone. I am having a doubt whether these persons know what a friendship means!! Do they want to refresh their friendship periodically( once in two seconds so that other can use the other second:) ) by saying "I am your friend" for several hours similar to the RSVP refreshing the soft states:). Yeah i accept that these friends are more possessive towards their friends and I praise them. But they should know that they are spoiling their times unnecessarily during their exams, project times. Dont you believe your friends. Dont you know that your friend is also preparing for the exams. Even the Indo-Pak problems are not discussed more than an hour :). Also using the cell phones continuously will affect the Blood Brain Barrier(BBB), a physiological mechanism that alters the permeability of blood capillaries so that some substances, such as certain drugs are prevented from entering the brain tissue while other substances are entered freely. There are some other physical disorders are also possible. Friends think atleast now and make your presence a valuable one to your friend and dont make them feel bad about you to others..meet you with my next "Drop"!!..bye
