That is rude of HER. Not you. If she only had a little money, she should have been upfront with the limit on spending. Plus, trashing a friend on Facebook is a no-no. How would she like if the shoe was on the other foot? Do you have a plan on how to address this issue with her?

Sorry about your dental bill. My husband and I truly understand them. Hopefully soon we'll be able to go to the dentist without it breaking the bank. At least your tooth looks very good.
