Husbands and wives have to get into the habit of doing those little things that mean so much. If a man comes home to find his wife asleep, he can cover her and tuck her into bed.
If a wife finds that her husband has fallen asleep, she can give him a little kiss on the forehead, even if she thinks that he will not be aware of it. Indeed, on some level his senses are working even though he is asleep and he may very well be aware of it.
The Prophet (peace be upon him) emphasized the value of these little things, “…even the morsel of food that you place in your wife’s mouth…” [Sahîh al-Bukhârî and Sahîh Muslim]
It may very well be that the Prophet (peace be upon him) was alluding to the expenditure of a man for his wife’s needs. Nonetheless, the Prophet (peace be upon him) chose to express it in the way he did for a reason. Most importantly, this is the way the Prophet peace be upon him) conducted himself with his family.
This type of behavior is governed by the tastes of the people involved. It may take some getting used to, but it really does not take a lot of effort.
A person who is not accustomed to such things may feel embarrassed just hearing about them and may prefer to leave matters the way they are rather than try to change his behavior and do things that he might see as ridiculous.
Still, we must be willing introduce new habits into our lives if we do not want our problems to go on forever.
