There’s a joke about a mother-in-law coming to visit her daughter and her son-in-law. The son greets her at the doorstep.
‘Oh, hi! How are you!’
‘Oh, I’m OK, just hopping over for a quick visit.’
‘Ah, I see. For how long will you be staying?’
‘For as long as you want me around.’
‘What, you won’t even stay for coffee?’
