You learned as a child that it is good, proper, and nice to share with others. This concept carries over to marriage, but it works a little differently than it did in kindergarten.
Let’s say, for example, that you like to occasionally eat a banana. You realize that Abby is not as fond of bananas as you are and rarely eats them. You stop at a convenience store on your way home from work and they have some great-looking bananas for sale. You buy two of them—one for today and the other one for tomorrow.
You get home and place your bananas on the kitchen counter. After dinner, you decide to have one of your bananas for a snack. Your wife asks, “Can I have the other banana?” Of course, you graciously say “Yes.” There goes tomorrow’s banana.
A few days later, you stop at the same convenience store and they again have some great-looking bananas. You decide to get yourself two of them—one for today and the other for tomorrow. You recall, however, that last time you did this, Abby ate your second banana. You decide to compensate for this and buy three bananas; two for you and one for your wife.
You get home and place the three bananas on the kitchen counter. After dinner, you decide to have one of your bananas for a snack. Abby does not ask if she can have a banana.
The next evening, after dinner, you decide to have your other banana as a snack. Abby still does not ask if she can have the remaining banana.
By the third day, Abby still has not asked if she can have the remaining banana. By this time, it has turned black and is inedible. You throw it out in the garbage.
Like I said, sharing in a marriage is not the same as sharing in kindergarten. Good luck figuring it out.
