When she gives you instructions on how to do a certain task around the house and you get so fed up, (because you know she is wrong but daren't contradict her in full flow), so you politely ask her to show you what she means.
"How am I supposed to show you if I don't know how to do it myself? Thats why I'm telling you."
When 'she' takes more than a few minutes to parallel park and eventually stope 12-18 inches from the pavement. I generally open the door and say 'I'll walk to the kerb'.
