Plenty of people know the joy of making spontaneous friends in a bathroom on a night out - but very few receive the kind of attention this woman did.
Mahri Smith from Ottawa posted a series of selfies with her friends and an elderly woman on Twitter - and her post has already been retweeted more than 73,000 times in just 48 hours.
The 18-year-old wrote: "This lady in the washroom, looking at me, said: 'I remember when my girlfriends and I would get dressed up and go out. I miss that.'
"So I said: 'Why miss it? We're all out right now aren't we?" Short story - we have a new friend."
