There are 3 times in ones life where the words you are using should be utter with upmost reverence and only after careful consideration. The first time is when you are getting engaged and ask a woman to marry you. The second time is when you actually standing at the altar saying your vows. However, there is a third instance where the words you are speaking shouldn't be uttered unless you are completely ready to stand behind them. And that is when you tell a woman that it is OK for her to kick you in the balls as hard as she can.
The reason why you should be prepared to commit to your words in all the above scenarios is because in each one of them, she is likely to accept your offer.......especially the last one. This is because in the first two scenarios with engagement and marriage, those only happen once in a blue moon. However for the third instance, those words for her are like a coupon that she can use to reak havoc on your life whenever she pleases without explanation like a coupon she uses at the grocery store.
