Manual and “T” line

When doing an unintentional model, if I become aware that I have a manual for someone (*cough* my husband *cough*) would it be appropriate to use one of the manual instructions as my “T” line?
As in “He should shower early when he wakes up before me so the bathroom is free for me to use.” (You said: don’t worry about petty. :D)
Thank you!
