Ines in the past I was very critical of your mother, but today she acted as any keyholder would have done.
Well if you had gone to your mother at 8:00pm I could see her talking with you and working with you. Maybe a 2nd shower that isn't very warm (Not Ice cold or anything like that just room temp)
BUT at 5:00 AM before work IDK I don't think spanking is right but I wouldn't be thrilled to get woken up unless you were dying lol. If I were your Mom I would also wonder what is the occasion all of a sudden???
