Her children and husband make her run all the time. She has to dance to their beck and call. Her children Doris and Cyril are spoilt children. They are also selfish and thoughtless. They don't pay that respect to their mother which she really deserves. Mr George also treats his wife rather indifferently and coldly. Mrs Pearson is condemned to drudgery. Mrs Fitzgerald, on the other hand, is a liberated woman. She is bold and dominating. She enjoys good time and is the mistress of herself and the family.
Mrs Pearson is tender and mild. When Mrs Fitzerald gives a heavy dose to Doris, Cyril and George, she can't bear it. She asks her to stop the drama at once. She presses her to change back their personalities. Mrs Fitzgerald is firm, solid and result-oriented. She sets all the spoilt members of Mrs Pearson's family right. She is a better judge of men and matters than Mrs Pearson.

However, lattice energy in case of sulphates, remains almost same with an increase in the atomic number of alkaline earth metals, due to the large size of sulphates ion. Hence, hydration energy only governs the solubility of alkaline earth metal sulphates decrease as the hydration energy decreases on moving downward the II A group.
On the other hand, in the case of hydroxides, the lattice energies are different because of medium size of hydroxide ions and decreases on moving from Be to Ba. This tends to increase the solubility and to overcome the counter-effect produced by the decrease in hydration energy. Hence, the solubility of alkaline earth metal hydroxides increases with increase in the atomic number of alkaline earth metals.

The Constitution refers to the three kinds of emergency given below:
I. Emergency arising out of external aggression or internal disturbance or armed rebellion or its possibility. (Article 352): According to Article 352 if the President is satisfied that a grave emergency exists whereby the security of India or any part of India is threatened by war, external aggression or internal disturbance, he may proclaim a state of Emergency. If the proclamation has not been approved within two months by both the Houses of Parliament, it will become ineffective. But by the 44th Amendment this period of two months has been reduced to one month and that such resolution should be by a majority of the total membership of each House and not less than two-third of the majority of the members present and voting.
After the approval of the Parliament emergency continues till the President revokes it by a subsequent proclamation. But it is provided in the 44th Amendment that for the continuance of the emergency the approval by resolution of both the Houses would be rquired every six months.
