TIFU I saw my neighbor’s house get broken in without realizing

My neighbor lives with her boyfriend and her house is often empty, she also goes on trips quite often so it’s not a surprise to see no one around or if there were it’d be difficult to differentiate if they come by often or not because of how little I interact or see my neighbor.

I live in a relatively safe neighborhood, it’s a block into a residential area from a large street in our city and there’s often kids walking to and from school because it’s within close proximity of 3 schools. I woke up and was making lunch and my kitchen window from the sink is the direct view of my neighbor’s backdoor and yard. It was in broad daylight and I see a guy who’s fidgeting with the lock with a toolkit and he did it so nonchalantly and with such confidence that I didn’t even suspect a thing. I just assumed they were fixing or changing their lock. Then I came back after finishing eating my meal, and I see them carrying things out of the house. They might’ve saw me or didn’t, I was just watching them move the television and other miscellaneous valuables. I might’ve slightly suspected something was wrong now, but again it was 1 in the afternoon and it’d be difficult for them to not see me coming in and out of the kitchen as I was making food. The sheer confidence in what they were doing completely overshadowed my suspicion of the whole ordeal.

Fast forward a couple weeks later, I over heard that their house got broken and lost some furniture, money and jewelry.

tldr: A neighbor who I had little interactions with and barely stayed at their home got their house broken into in broad daylight and the sheer confidence of the burglars who saw me in the kitchen while committing the crime made me oblivious to the whole situation.
