Are signs ever real when ttc? 🤔🤞🏽

I’ve had some wired stuff happen lately while we’re trying to put our rainbow bun in the oven and I was just wondering if signs are ever really “signs”. A guy at the grocery store walks past my daughter in the cart and says to me and my husband “you know what she needs.. a little brother”. It was random as hell but I told him that’s exactly what we’re hoping for and he laughed. Then he told us he ended up with 4 daughters and we all laughed. Hoping that wasn’t the real sign lol🤣🤣
