I cant tell if I'm BU 
I attended a destination wedding this weekend. Shared some pictures with MiL and SiLs on a private whatsapp group.
SiL2 made a collage out of my pics and sent it to me, I thanked her for the sweet gesture. Next thing she's gone and made that collage her whatsapp DP... is that weird? AIBU to find it weird??
She also from time to time puts my DS' pic as her dp despite having her own DC.
