Implementing Queue using Two Stacks Strange Error

For some strange reason, whenever I print the size of the reversed stack (for testing purposes), I keep on getting 7. Why is that the case? Shouldn't the reversed stack be empty since nothing was pushed to it? Thanks!

public class QueueViaStacks {

    static Stack original;
    static Stack reversed;

    // push everything into the first stack
    public void enqueue(Object item) {

        // create stack if it is not yet created
        if (original == null)
            original = new Stack();

        original.push(item);

    }

    public Object dequeue() {

        if (reversed == null)
            reversed = new Stack();

        System.out.println(reversed.size);

        Object temp;

        // reverse stack by copying everything from first stack to second stack
        if (reversed.isEmpty()) {
            while (original != null) {
                temp = original.pop();
                reversed.push(temp);
            }
        }

        return reversed.pop();

    }

    public int size() {

        return original.getSize() + reversed.getSize();

    }

    public static void main(String[] args) {

        QueueViaStacks stack = new QueueViaStacks();

        stack.enqueue('T');
        stack.enqueue('E');
        stack.enqueue('S');
        stack.enqueue('T');
        stack.enqueue('I');
        stack.enqueue('N');
        stack.enqueue('G');

        stack.dequeue();

    }

}

Below is my Stack class:

public class Stack {

static Node top;
static int size = 0;

public void push(Object item) {

    Node t = new Node(item);
    t.next = top;
    top = t; 
    size++;

}

public Object pop() {

    while (top != null) {
        Object temp = top.item;
        top = top.next;
        size--;
        return temp;
    }
    return null;

}

public int getSize() {

    return size;

}

public boolean isEmpty() {

    if (size == 0)
        return true;
    return false;

}

public void print(Stack stack) {

    Node temp = top;
    while (temp != null) {
        System.out.println(temp.item);
        temp = temp.next;
    }

}

}
