['Have you noticed the trends with engagement proposals and save the date YouTube videos?  I find them to be so romantic.', 'I have not seen those but that sounds cute. Are you married?', "No and have no intentions of getting married.  However, I don't have any problems with celebrating with those who make that choice."]
Yep there's nothing wrong with either of those things!
Even though I have no intentions on getting married, watching proposals or weddings make me feel really warm inside.
