The common "doh" moments I can remember off the top of my head go something like this:
1. Went to buy a CS set and buy the entire snowboarder set and realize that I bought the male one and I only have female characters..........

2. Sent 100m to a friend.... Didn't capitalize his name.... Sent it to some random person I didn't know..... .________________. At least they had a good day.
3. When I first started playing... flyff was my first mmo and I was killing aibats and didn't realise there were higher lvl mobs.... For some reason it took me a while to get past level four.

4. When I first got my broom I spent about an hour trying to ask people how to get off of it... everyone I talked to thought I was kidding and 'lol'd' at me. TT_TT But I was totally serious.
5. I remember talking to a guy I thought was soooo cool and pulling the common typo " sex" (instead of sec for those of you who have been lucky enough not to make that error

) ... He still makes fun of me for it... /wrists
6. After quitting after v7 started playing again recently... sold spros for 4m each.........

How was I supposed to know the flyff economy got totally inflated while I was gone. I thought 4m was a high price....
7. Forgot to put my gwand back in the bank before I PvP'd... way back when you dropped stuff when you went red and got killed. -___-;;;
8. Joining orange...
