Sad parting of a good friend

Few nights ago I took munchkin's car for a final wash and I filled her up with petrol. It was our last trip to the petrol station because the very night the car was to change owner. We or rather I sold Munchkins' car because we decided to use the money to provide more for our Irfan. It saddens me to have to sold the car that I bought for Munchkins. I wonder I can ever make up for it.
