Check out this scenario people
you have a friend of the opposite sex and you guys were quite close in college. u guys finished school and parted ways and lost communication. u are now married and ur spouse has been away for a while. u stumble upon this old friend of yours and u guys started catching up on old talks. in the middle of the catching up, ur spouse say, walks by and sights the both of you. will u follow ur spouse that you havent seen in a while or continue the discussion with ur friend? u cant combine both. (no strings attached with the friend)

I would ask the both of them to walk me home

I would follow my spouse of course. And my friend being a true friend would understand me and know that I would be following my spouse.

Spouse of course, and thats shouldnt be an issue with the 'friend'.
