This indicates that it maybe easier for your W to maintain friendships if there isn't a daily closeness. Sometimes it is form of insecurity others it is a genuine desire to have alone time. Does your W revel in her own company? Does she seem to have a push pull relationship IRT being alone?
I don't mind the sun sometime
The images it shows
I can taste you on my lips
And smell you in my clothes
Cinnamon and Sugar
And softly spoken lies
You never know just how you look
Through someone elses eyes
