Really sorry to read some of the previous posts, my thoughts and best wishes are with you.
My daughter lost another tooth the other day and as usual she put it under her pillow, with the tooth fairy bringing £2.50 by the morning.
On trying to spend it on sweets at the self service machine in sainsburys, her £2 coin kept being rejected. The member of staff on duty then came over and said he thought it was a forgery. To his credit, he changed the coin for another from the till, but this has still left my daughter thinking that the tooth fairy is into circulating counterfeit currency.
