Love is supporting your husband through his mini identity crisis when your mum calls your sister's boyfriend for tech support instead of your husband.
And also helping husband trouble shoot the problem so he can call his mother in law with the solution and receive a text message (from newly sorted out phone) that says 'you're my favourite son in law'.
And refraining from commenting '…for now' about the message.
Also, the eldest quoted a newly learned (abridged) bible verse:
'Love is kind, it is not rude bum'.
We'll work on the application I suppose.
