she already has a (cell) phone... this was another !
Is there any way dialled numbers can be extracted from the phone ??? The call history menu in the phone has been deleted, apart from a few numbers...
1, our home number (why would she call our home number for 1min 15sec ?)
2, her female friends' number

If there are only 3 calls made from a $20 credit - there are missing numbers !

PS My wife is one that backs into a corner when confronted about something and will "clam" up and become defensive ...
