When I was walking to the cathedral, I saw a couple walking in front of me. Suddenly, they stopped and the woman opened her bag and then they returned toward me. Then they again passed me and walked somewhere.
I saw a suspicious Turkish car also.
When I was at the cathedral, there was a woman with a pink hat sat in front of my bench. After the communion, she sat on the bench few rows to the front and she asked me to sit next to her. I refused as I left my HP bag at where I sat. It was as if someone tricking me to forget my bag at the church. My computer was safe.
By the way, I found my SD card slot filler plastic part was in my computer bag. It has been gone from Hostel ZemZem trip in Sarajevo for the Pope visit this June. I thought I forgot that part on my bed in my private room in the hostel. I searched my bags and I could not find it. It was returned in a strange way.
