Having gone through the Effing Fours twice now, I can feel your pain! It is definitely the most challenging age (my oldest is now 6, so I know there are more challenges to come).
I had a a similar instance with my 2nd DD at the park, I wound up dragging her out of the park as well. Not a pretty scene...
It will get better - I've found that once they turn 5 the "switch" goes off and they are a lot easier to deal with! :)
I've been dealing with this with my daughter and she's four as well. Most of the time its a story about something that happened (that didn't really happen), but she has also lied about stuff she's done because she doesn't want to get in trouble.
I take it pretty seriously, and I'm not happy about it. I also remember lying as a kid, and I know that most kids do it, but I want to make sure she understands that it is not acceptable.
My girls are 17 months apart. When my younger one was a baby, they were in separate rooms. I felt that her schedule would disturb my oldest. But once they were on the same schedule, they really wanted to be in the same room!
So, now they share a room, and they love it. They are now 6 and almost 5, and there are no disputes over space or anything like that. They just love being together...It was the best thing we could have done.
Now - I know as they get older those feelings are going to change, lol. But that's okay - I think having to share a space with a sibling teaches them a lot. I was an only child for 10 years, then had a brother, so I never shared a room. To be honest, I think I had a harder time adjusting to college because all of a sudden I had to share my space with 7 other girls.
This is such great advice, and so neat to see how far you've come in the 6+ years. Everyone starts from the bottom; it's how you learn from the mistakes to make things better that sets you apart from the rest.
Awe, I'm remembering my girls' first days of preschool while reading your post. It's such a bittersweet time! I cried when I signed the papers at the school, when I dropped them off, and when I picked them up! lol
I'm so glad I'm not the only one that goes insane when their dog licks and licks and licks....my yorkie does that and it drives me crazy!!
