Give a smile
Things are not going that well last one week or so. We always get into disagreement. The congeniality that we had earlier seemed to have vanished. I guess the honeymoon period is truly over. Sometimes when things are not going that well, your mood sways up.
I read on a magazine that a simple tip to defuse such tension is to give a smile when things are going bad. You may think it is impossible but sit up (or stand up) shoulders back and smile. Watch the world change in front on you. What was bleak is not so bleak. In fact nothing is as bleak as you think it if, if you just smile. Try it. Give her a sincere apology and things will be back to normal again.
Sometime we guys just have to give way.
