There are so many potential stumbling blocks and pitfalls - money, jealousy, each other's friends - but one subject that can be more awkward than most is the topic of babies.
Depending on your age, you may be at very different places in life, and the discussion about potentially having kids together is not one to be broached too soon, or taken lightly.
...unless a viral tweet tells you to do otherwise, just for the sake of it:
Kelly here dared her followers to take the bold step of demanding a baby from their boyfriend, no matter what stage in the relationship they were at, or their feelings about having kids in general.
The tweet soon blew up, with over 8,000 responses showing some amazing screencaps that had resulted from the dare.
Obviously, we don't have the time to go through all of them, but we handpicked 20 that will make you laugh. Enjoy!
I love this response. He seems like a pragmatic kind of guy!
When you're being all firm and dismissive, but then your insecurities kick in...
I mean... this is really, really sweet, but I can't help but wonder if 'hygiene school' was a typo of some kind. Either way, I bet she wasn't expecting this response!
Starting a family is important and everything, but we're just about to go into the final season of Game of Thrones, so get your hormones in check.
It would be a conceivable get-out clause, if it weren't demonstrably false. Try again.
This is just so cute and wholesome; I can't cope. I can't help but wonder whether this is the response she wanted though. Be careful what you wish for!
Matthew wasn't having any of this. I'm sure most of these dudes must know that their girlfriends are just goofing around here.
The one thing that will stay with me about this exchange is the word 'peep' used in this way. That's a new one on me, but I'm going to use it for the foreseeable future.
If there's one thing that's guaranteed to pile on the pounds more than simple carbohydrates, it's having a baby inside you. Make your mind up!
This is a perfectly reasonable response. You can always carry the pooch around like a baby and dress it in ridiculous clothes! Plus, you won't need to start a college fund.
Again, why have a stinky baby when you could have a stinky dog? Much more useful!
Okay babe, fine - let's start a family. But first, I need you to acknowledge how amazing these nuggies are.
Anthony knows what's up!
This is wholesome as hell, and it looks like she's found a good guy here. But the question remains - is this the response she wanted?
A classic response, but that needn't be a disqualifier these days! You guys have plenty of options.
Well, at least she's not fussy!
A baby could end up costing a lot more than a Ferrari in the long run!
Can anyone say "D'AWWWWW"?
Some people are all business!
Not a moment's hesitation I guess some people just leap into life head-first, huh?
