You can only have a rainbow if it rains.

The only difference between a good day and a bad day is your attitude.

Dennis S. Brown
 
You come home from work feeling hot, tired and cross after a day of being snapped at by your boss. Your journey home is a nightmare, with what seems like half of your city on your bus, squashed into every available space and elbowing you in the ribs. You snap at the children when they play with their toys or music a bit too loudly. You get irritated when they don't sit and do their homework when they ought to. You greet your partner with a less than happy smile, and you burn the dinner whilst juggling the washing basket and sniffing loudly about how "some people" seem to think that "this is a hotel" and that they think that they don't need to help.
 
What have you done? You've spread the bad mood. You've shared the misery, spreading it out like a fungus so that the entire family goes to bed cranky.
 
Or......
 
You come home a bit tired after a day of your boss snapping, but decide to leave that behind you at the office door and walk home in the sunshine. You walk tall and by the time you're home you're ready to greet the kids, get changed into a fresh pair of jeans and t-shirt and start organising dinner.
Your partner comes home a little later, gets himself changed and fills the washing machine as you have a rota and it's his turn. He always supervises homework, allowing you to get on with cooking a healthy dinner for you all.
 
Which scenario would you prefer? The difference - your attitude.
