LPT: Put a smile on and return the warm greeting when coming home from work/school/travel.

Including your pets. You may be tired, aggravated, angry, whatever when walking through the door but your family is just happy to see you. Embrace it and enjoy it while it lasts because it won't last forever. Eventually the kids move out, the flame dims in your marriage and the dog dies. You will miss it all. Especially the damn dog that pissed on your shoes every time you came home.
