Abrasion is the process of scuffing, scratching, wearing down, marring, or rubbing away. Two bullets struck SA-500D's third stage marring paint and leaving dents. Here, Narasimha Sastry swindles by marring the voice of Viswanatha Sastry. The only thing marring this otherwise excellent episode was the presence of Nikki and Paolo. Relocation for these particular TCKs has shown to be particularly marring for them emotionally.
