How to get rid of stupid Winston (The Butler):
The better way:
1. Go to the kitchen
2. Use the switch to open the fridge
3. Lure the butler inside
4. Then immediatly get out and use the switch again to lock the butler inside.
This way he can't escape, but there's another thing you can use but he always get's you again (Using the kitchen door).
The not-so-good way:
1. Go outside to the big gate
2. Wait until he's right beside you
3. Then sprint back into the house
4. Once you're in the house, quickly use the switch to close the door, so as long as you're inside he won't bother you!
*Remember, this trick is only useful if you want to get rid of him just for a while*
And there's one last trick, but I didn't try it:
1. Lure Winston into the basement
2. Quickly shut the door of the basement
Enjoy your Winston free house.
