To think the woman sat outside my office could......

[whoopsfallenoveragainandithurt]

blow her nose rather than drive me mad sniffing every 3 seconds?

Offer her a tissue! It drives me insane as well when people constantly sniff!

Say ooh you've got a bit of a cold haven't you?

Maybe it's because she's outside your office. . . invite her in for a nice warm cuppa and throw a shawl round her!
Poor cold thing
