Just noticed, how awkward would it be if your dad and his Mum had a child after all four of you got married.

"I'm my own grandpa..."

I don't understand how everyone fails to understand this point. Firstly it is weird to be married to your step brother/sister. If they were cousins by marriage or something then i wouldn't think its a big deal, but seriously, being married to your step sibling is sick enough of a thought and the person is your SIBLING, blood or not, that is still a brother sister relationship. If you can get over that part fine, but think about the parents having another child. They will both have the same brother/sister. Think how gross and awkward it sounds to have a same biological brother/sister as your boyfriend/husband. Think how weird it would be if your biological(half) siblings were married to each other. The parents shouldn't have ever looked at each other in that way EVER. That is just such a wrong thing to do to your child. Totally lose their kids trust. People saying well they're in love, well for one like i said they should have never looked at each other like that and two, there are plenty of other people to fall in love with.

the grossness is ALL in your head. they arent related, and most parents of adults old enough to get married arent old enough to have kids, and even if they are, nobody here mentioned kids, so why is this being discussed? this country is so stupid about things like this..the only reason incest is "wrong" is because it breeds deformity. i mean, we accept that woody allen marries his adopted daughter, and we accept all the time that people who have different parents but grew up together date and get married, so why is THIS scenario even an issue? this is stupid

oh my god i want some cake.

That was my thought :D ^^

tell them that's retarded

You are completely over-reacting. First off, the only way they would have a "brother/sister" relationship is if they had been step-brother/sister for years, not now after they are already engaged and they didn't know that the mother and father were dating each other. Second, the parents didn't do anything to these kids, they cannot help it that they became attracted to each other, and again, there is no long time brother/sister relationship between these two that will cause them to be messed up. Stop trying to psychoanalyze things that you quite obviously know nothing about.

My friend is 23, and her boyfriend is 24. Thier parents got married a few months ago, and its not wierd. Many people, especially when you haven't been "siblings" long, NEVER think of the stepsibling in a brother/sister way.

In teen mom catelynns mom married tyler's dad and they were engaged and had a kid together.

how is that funny...it sounds sick n u'd have to explain every detail to ppl wen u tell them O.P. : u got engaged 1st...its urs!! tell them to just stick to dating or something... thats kinda wrong o.0 but enjoy ur cake...dont choke!!

It's a big deal because now, they would be considered stepsister and stepbrother.

Not by blood

no just step mother

81 you forgot the "in-law" part

Then it should be posted on 'I had a tad awkward moment'.com

lol nice

thats exactly what i first thought of when I read this FML, and it's funny that when i read "his mother and my father", i knew what the FML was already.

lol i loved that episode

I thought of that fresh prince episode when I read this.

it's so totally like Gossip Girl (but then with the boys father with the girls mom)
