As a side-note to this, Never, Ever tell dad the following:

There is something wrong with my car. I'm bringing it to the Garage

There is something wrong with the light in the bathroom

There is something wrong with my boiler

I have lots of room in my house (Insert crap here...quite literally. Especially if they have a key to your home)

Um....anything that they can have an opinion on. I love my dad to pieces, but yes dad, there are some occasions when I do know what to do. You brought me up, I've spent the last 26 years listening to you and hearing you talk about fixing things. If I want your opinion I would add "What do you think I should do" at the end of those sentences.

Also, never say "I know, Dad" That leaves you open for a whole 'nuther argument! (By the way, the best retort to the counter strike from Dad which is "You know everything, then, do you?" is "Yes, actually, I do." It's very hard for them to come back with anything after that. Oh yea, and remember, once finished saying that, duck. Really, really fast. Or run. Whichever floats your boat...
