Gents, what would you think if your g/f came home from a drunk night out with her knickers inside out?

my g/f came staggering home last night, she fell on the sofa with her skirt up in the air, i noticed her knickers were in side out, so i asked why this was..she stood up kicked my dog & staggered off to bed slurring some nonesense...i asked again this morning before i went to work but she just blanked me...what do you recon?
