Why do some masjids feel so cold and unwelcoming?

Salaams everyone, I wanted to share something that's been on my heart. It's not really about me, but I feel like our ummah needs to do better when it comes to being welcoming at the mosque. I used to go for taraweeh regularly when I was younger, but life got busy. Now that I'm more free and have started going again, the way some people act just makes me not want to go. For example, in the sisters' section, some women have young children who might play a little. Personally, it doesn't bother me, but I get that it can be distracting when you're trying to focus on your salah. The other day, though, an older sister got so upset with a mother because her kids were playing, and she basically started attacking her verbally right there. It just made me sad-if you have an issue, couldn't you address it kindly and privately instead of embarrassing someone in front of everyone? It reminded me of another time when I was at an airport with my mother. We were in the prayer room, and we whispered briefly about something important before starting our salah. A sister who was reading Quran turned around and got really angry at us for talking, even though we weren't being loud at all. I understand she was engaging with the Quran, and she could have just politely asked us to keep it down if we were disturbing her. But her reaction felt so harsh and rude, especially since we didn't mean any disrespect. I just feel like sometimes people forget their manners, and honestly, that kind of attitude can push people away from Islam. Our character is just as important as our worship, you know?
