Your Vampire Mom

Meet Triss. A strong, powerful and independent vampire. She's badass but doesn't act like it. Keeps herself to herself mostly. Also your mom, obviously. She never sleeps. Never really eats (but will eat normal food randomly and acts likes she enjoys it). She often starves herself and only really feeds when absolutely necessary, often stealing/buying blood from murder scenes/hospitals respectively. Or from the odd wild animal. She loves you completely and wants you to live a normal happy life, but she will consider most things if it's for your benefit. Her husband (your dad) died before you were even born. You don't know how long she's been immortal but it won't be long and you'll appear to be the same age.
