Agree with @TinklyLittleLaugh this is a very sad and depressing thread. I am taken aback by the amount of stuff so many people haven't done. There are such a lot of things that lots of posters seemingly haven't done, that I wonder what they actually have done. 
Seriously, everyone I know has done at least some of the things that people claim to have never done. One poster claims they have never been for a job interview?!
I don't know a soul who has never been for a job interview.
Some claim also that they have ... never celebrated ANY anniversary, never learned to ride a bike, never been to a party, never took a driving lesson, never learned to swim, never been to a hen party, (or a Christening,) never been on holiday with a friend, or lived alone or with friends, never played out with friends as a youngster, never had a Valentine's card, never been a bridesmaid, never done any travelling, never had a teenage romance/holiday romance, never had any friends............
As has been said, this thread makes for very sad reading.
I am just a bit
reading this thread....... We only get one life, and many people are missing out on so much........ 
Also quite stunned at the amount of posters who have never been married, but have been with a DP (who doesn't seem to want to get married,) for decades! You deserve better. Come on!!! Start living the life you deserve, and do some of those things you have never done or achieved!
Yeah I know 'everyone's journey is not supposed to be the same yada yada....' but honestly, everyone I know has done at least SOME of the things people claim they have never done (on here!)
Of course not everyone is going to have done EVERYTHING, but according to this thread, some people have done nothing. Bizarre. 
And please don't call me smug or judgy or anything, I'm not; I am just shocked that so many posters are claiming to have not done so many things. I just don't know anyone in real life like this.
