Ending in reverse

Well just returned from cruise this morning. Saying it was good...well not really...saying it was bad also doesn't fit the bill. I realised my family has a very different characteristic then most family...well for the matter of fact, its very unlike any individuals even. Usually returning from a holiday or breaks follows a good rested feeling to a stress and not so good...till even bad mood due to returning to the normality of life either in work or daily life. But then for my family, the tension and bad moods and pissing all usually comes from each other....that suddenly everyone gets irritable or pissed.....hmmm strange right?!!?!..hmm I also cannot understand this.
