His sister was technically the first person to officially know since she had just got to their family cabin and saw it happen but the first person I told was my sister. I immediately called her to tell her!
Tried to tell my mom first but she didn't answer her phone. We were on vacation with friends so they noticed the ring at dinner and ended up being the first people we told. My sister was next to find out since my mom still wasn't answering her phone.
My sister! She's my best friend, so I wanted to tell her first. But it was a race with my FH posting our engagement on Facebook at the same time I was calling her!! I knew she would see his post, so I'm like "wait! I have to call Amy before you post!!" lol Luckily, I reached her before she saw his post. I told her about it later, and she agreed she would have been pissed if she'd seen it on FB before I called her!
Well my parents and his parents knew a month before he was going to propose. So when I called them they weren't all that excited lol. My mom even knew the morning of. I called her first and she said "FINALLY" Then I called my dad and step mom. Then I called my grandparents who were the only ones close to me who didn't know ahead of time. It was more fun to tell them since it was a surprise. About an hour later we were to meet FH's family for dinner, so we officially told them then even though they already knew it was coming. Then after dinner I group texted my closest girlfriends and posted it on facebook! Ah crazy
My FH set up this elaborate plan to get all of our friends together for a picnic at another friend's house. My sister and BIL were visiting from Georgia and came too (I just thought they were coming for a fun time) but my parents knew it was happening. So technically like 30 people saw it happen. Lol I then posted a picture of my ring that said "So this just happened" and everyone else was informed. Lol
