You know you play UO too much when you...
... try to eat an entire chicken leg by double-clicking it (tapping it twice)
... dress up as a UO character for halloween or you try to look like your character every day
... try to log out of the real world
... build your dream house to look like your UO house
... want to name your kids after your characters
... are drunk and you *hic* often
... try to buy a horse so you don't have to run around everywhere
... are with your non-UO playing friends and they don't understand you half the time (or do)
... get a little nervous upon remembering that none of it is real and will in no way help you in life
... go to the bank and are shocked to learn that you don't have 300k
... are late for work or other engagements cause you have to find a safe place to log out, are participating in a quest , or have just gotten killed and are trying to get your stuff back.
... wander if your hungry or not , cause you've not seen any messages saying You are Starving.
... see birds land in the yard or what not, and are thinking there is 25 feathers.
... see a rabbit in the yard , and You Yell RUNNNN FOR YOUR LIFES!!!!!!!!!!!!!!!!!!!!!!
... think of items, dead plants, ect. decaying instead of having to be cleaned up, or decomposing.
... are playing Taboo, Scategories, or some other word related game with friends and you try to describe it using UO related terms and items.
("You're on this when you go from the bank to the mages shop." "You know that thing in your house that is very prominent." "Do you remember when we were hunting and that one baddie was shooting you from afar with his...")
... turn down every female you meet because they don't have the same physique as the female in the character window.
... watch your character macro instead of TV.
... look at your roof and think Rel Por and then kick yourself because you don't have any bloodmoss or mandrake root.
... learn and write frequently in the Ultima Alphabet.
... are hungry and you want fresh food, and you fumble through the crap around your desk looking for your spell book, garlic, ginseng, and mandrake root.
... scribble on a peice of paper then think that'd be a great graphic to have in UO but then remember how much of a pain in the butt it is to figure out how to add it to the mul files.
... wish you had a rune to mark in your girlfriend's room so you can come visit whenever you please... But then ask yourself what you were thinking because obviously the anti-magic field would block the spell.
... think of items, dead plants, ect. decaying instead of having to be cleaned up, or decomposing. (I once bought a rose and put it on my girlfriend's car's windshield at night, and I asked a friend, "Do you think the rose will decay by morning?")
NOTE: Some of these are my original thoughts and or experiences, but others were found on other websites.
