That's ma maw. She's adorable.
My mum was telling me she was getting telesales calls that were bugging her because they'd start talking as soon as she answered the phone and then wouldn't stop. On this occassion a gentleman of the "asian persuasion" was trying to sell her something. On and on he went. On and on and on and on. He wouldn't stop. So she waited and belted out a loud, sing-y "LAAA LAAAA LA LA LAAAA!"
He hung up.
