I remember back in my dating days one of the ways for me to flirt with someone was to offer the shoulder or back rub. Who doesn't like a little bit of the human touch. Well, I'm still giving back rubs, but it's to my family members. Tonight as I put my kids to bed my 6 year old daughter begged for a back rub. She likes for me to rub her back and count to 100 as I do it. Since she's in first grade I counted by 10's and immediately she said, "No fair." I then counted by 5's. She asked me to count by 2's. Pretty smart for a 6 year old to know that the smaller I skip count by the more time she'll get.
My son likes for me to write letters on his back. I ran through the alphabet 2 times, gave him a kiss and said mommy would be in after she got home from praise team practice. It worked. It actually works best if we do it after 9pm. Otherwise he's still wound up and it's not productive time spent.
My wife will throw the lotion out on the bed when she is hinting for some TLC. When she bought me the massage book for a gift, I really wonder who the gift was really for. She also likes a little bit of time spent on her feet. My daughter likes the feet to be rubbed also.
That said, we all love concentrated one on one time. Doesn't matter if you are a kid or a spouse. Now I'm not going to offer to rub my poker friend's backs. Just think how our relationships would be better if we unselfishly tried to meet other people's needs on a daily basis. Start the cycle and eventually the favors would be returned. Try it!
