Some of Lisa's expenses make no sense at all.  I wonder if the Globe writers are snoozing on this one . 
According to the profile, she spends $100 per month on groceries plus $75 on dining out.  That is very difficult to imagine. 
Meanwhile, the same profile has her spending $710 per month on group benefits at work, which seems monstrously high for a single woman earning $75,000 per year.  That's 11% of her gross pay.  
I don't buy it Globe FF.
