Sandra looks after the numbers at b4b. Originally from Colombia, she came to the UK to study English over 20 years ago. She's a big fan of U2 and being a working mum to twins doesn't get much spare time but when she does, she loves nothing more than walking through the woods on her own, preferably eating lemon flavoured crisps - a Colombian delicacy by all accounts! Her superpower would be the ability to fly so she can pop home to give her mum a quick hug whenever she wanted.
