she admitted she lied

She comes to me crying (Venita) and admits to lying to me...
then doesn't tell me what she lied about...

2 days later (last night) she admitted it was the power bill she didn't pay...

I gave her almost 500 dollars to pay two bills...
one was 325 - she paid 279 and never told me... AND then the power bill - she had 150 from me to pay that... and she never paid it...

what does one make of this?

*cries*
