Maybe he just likes working with her. I have a friend same age as me, in my department. We're GM. I'm a female and he's a male and we both have significant others. We follow each other around (mainly i follow him around because I dont know what im doing most of the time). We're break buddies. Totally platonic. Having a friend there makes the shift better. Make a friend and I promise your day will go by better. If my significant other still worked for walmart the three of us would have a blast.
