Oh your brother was mania for tennis to the extent that he carried tennis equipment in his car wherever he went. It is rare case even for tennis amateur, but I know such a person too.

$30 monthly is not a small money to me either if it does not give me the corresponding or more benefit.

One thing that most amateur club tennis players agree is that they feel ultimate happiness when they are playing tennis. They forget every other real-world worries and agony when they are focusing in tennis. This is why I put $30 every month in tennis club membership.
