TIFU by taking my kids for a walk

My oldest child has been sick the last few days, so I decided to get him some fresh air and go for a walk. I have two kids so, I strapped my baby into their car seat and plopped it into the stroller. My oldest wanted to ride his bike, so I got it out and off we went. I let him decide which way we would go and he was happy and having a good time. Something I need to add is my son doesn’t like dogs very much. They are a bit too loud and unpredictable for him, so whenever he sees one he tries to stay away from it. While we were walking my son sees a truck and he loves trucks, so he stops to look at it. Unfortunately, he did not see that there was a dog in the yard right next to him. It was behind a fence, so I didn’t have anything to worry about, but I knew that he was going to be startled. I called out to him and said, “Look out Baba”. He then turned and saw the dog and instantly freaked out and started crying. I stopped the stroller and gave him a hug, but then the stroller rolled off the sidewalk and into the ditch, tipping it over. Luckily I had strapped the baby into it, but they started crying as well. I then looked over and the owner of the dog was sitting on the porch and he was laughing at me and the truck had someone inside of it and they were also laughing. So at that point I was around the corner from home, had two crying kids, and felt like the worst mom ever. I just picked up my toddler and walked away in shame. Both kids are totally fine, but now I am extremely embarrassed. Moral of the story is, don’t take your kids for a walk unless you are prepared to be judged and laughed at by others when you make a mistake.

TL;DR
I took my kids for a walk, the stroller rolled into a ditch, they both cried and I got laughed at by strangers.
