I once posed as my mother over the phone to get my sister out of trouble, her teacher was calling in to essentially tell on my sister. We pulled it off.

I was trying to sound completely different than myself cause that teacher taught me too, I don't know what the hell happened but a British accent came out.

My girlfriend did it all the time in high school; that would explain he horrid attendance record, complete with 50 something absences.
When crying don't help
You can't compose yourself

An honest verse of longing

yup I phoned in as my dad, and have also forged my mums signature many, ma ny times
