As far as happiness goes, Alex thought he was content with his life now. Life wasn't a bed of roses, but it really wasn't any thorns in his way anymore. He wakes up each day with newfound hope and courage. He works hard till late at night and reaches direct home after his long tiring day at work, eats a simple meal, and off to bed he goes.
To others, it would seem like nothing has changed much but Alex knows everything has changed, everything, including his relationship with his parents. He hasn't become the lovey-dovey son, his parents would be worried about and his siblings would look at him strangely. No, he much to everyone's annoyance stayed the same but changed at the same time.
