Don't Worry, Voicememo, she only likes to be negative and complaining and not helpful in any way when she comments (nearly) every time. Only just inputs her pessimistic and downtrodding tone and opinion with out ever giving any helpful information usually needed for the person inputting a question.

And I would LOVE to see what level digging my chocobo is too, since like you, I have Woodworking and P.logs are best attained (almost) freely with digging, along with a LOT of 'metal' ores in desert areas (Gold, silver platinum, orichalcum, iron, mythril, etc...) which i used to lvl up my goldsmithing mule and smith mule.

Saved me a LOT of gil, though it may have taken me a little longer than someone who just buys them from AH and wants that "Oh i need that done as fast as possible because i have no patience." attitude.
:: Ergo, she has no patience enough to lvl up chocobo digging skill, but has plenty of opinion about something she (probably) doesn't do.
