So some parents might react differently but im quite proud of my daughter, she peed on the floor and came to show me what she did. Its the thought that counts.
That would make me mad, do you have carpet or hardwood?
Its carpet, it didnt bother me because shes in potty training stage and I am just glad she came to show me she did it so she realized it was wrong! ( lol ) 
Oh, well that is a good start then!
