Whenever I tell one of my friends happy news, this is what she says. Like her and the rest of my friends have been speculating together about when it would happen.
eg I’m engaged - ‘We knew you would be! We actually all thought he’d propose in XX (last holiday)
or recently I told her I was pregnant and she said ‘We knew it!’
AIBU to find this a bit annoying? And why would say not just say congratulations etc? Even if I don’t know someone very well, I still know to act excited for them about their happy news!
