Venting 😒

So I haven't had a rant in a little while. Lmao. But anyways, I do NOT understand why on some postings, girls tend to ask questions about pregnancy, and when they receive an answer the poster gets rude or even tries to tell them different. Like why in the HECK did you even post the damn question if you wanna be a f'n know it all! Theres no need for your question if you already know the answer. Ugh. 😑. 
Alright, rant over 😁
