Dear Jaskaran, I feel sorry about the vandalism on the laptop

charger

that I collected from you.

This

is a result of my poor decision when I plugged the

charger

into a lower socket, which happen to be accessible to my cat, Cove. Usually, I make sure of locking Cove’s playpen before leaving the house. That day, I happen to be in a rush to go to the mall that I forgot to do that. Unfortunately, Cove got out, rushed to my room looking for me and found the

charger

instead

and before anyone could get there, the damage had already been done. I plan to give the

charger

to a technician to fix it. If it's not fixed, a replaced

charger

will be ordered from the company itself but it might take some time. I felt really bad about

this

misfortune. Please find it in your heart to forgive me. Warm regards, Navdeep Kaur
