If God has you together, you enjoy discovering the surprises, no matter how much you have in common or not.
You need to be able to share closely with all our brothers and sisters in Jesus. This can include taking an instant interest in anything so you can talk and share with each other > read what Paul says about becoming >
"all things to all men" >
in 1 Corinthians 9:19-23.
From this, I see I do well to take an interest in anything about my lady friend, so I know what she is doing, what she might need, and because I value simply being with her.
When I was a kid, dogs were an idol for me, partly because I was such a jerk and screwball who had little social activity. Then in Jesus I knew I needed to care about any and all people and find out how to love each one. So, dogs became nothing to me.
But with loving people came enjoying their dogs and at times helping care for them. And now I see how dogs can have unique personalities and be very worldly like people . . . often being clueless about how to love, like plenty of people are maybe very charming but clueless and only using people for what they want.
So, with Jesus and loving I have developed different interests and ways of seeing things.
