Sympathetic Blonde

A blonde goes into work one morning crying her eyes out.
Her boss asked sympathetically, 'What's the matter?'
The blonde replies, 'Early this morning I got a phone call saying that my mother had passed away.'
The boss, feeling sorry for her, says, 'Why don't you go home for the day? Take the day off to relax & rest.'
'Thanks, but I'd be better off here. I need to keep my mind off it & I have the best chance of doing that here.'
The boss agrees & allows the blonde to work as usual.
A couple of hours pass & the boss decides to check on the blonde.
He looks out from his office & sees the blonde crying hysterically.
'What's so bad now? Are you gonna be okay?' he asks.
'No!' exclaims the blonde.
'I just received a horrible call from my sister. Her mother died, too!'
