OK - just got a txt from Mom (stuck at the airport in Cali b/c she missed her flight - but that's another story.) In this text she said (and I quote) "Bought fee a spires."
After much thinkin, i have decided that she was an unsuspecting victim of Autocorrect.
For now, I'm running with the theory that fee = Fi, and she just couldn't get Autocorrect to leave well enough alone. Any idea what she was trying to let me know she got her youngest grandaughter?
