The fact I absolutely can't keep my mouth shut when there's something I don't like. For instance; there was this old lady on the market and my sister lost her key card she needs to get access to the trash container. So it was very crowded and loud noises. When me and my sister were standing still for a moment that old lady came up with a very angry face snapping at my sister how my sister lost her card and she found it and was following us and yelling Miss Miss but we didn't hear her. My sister said "thank you". The lady gave her a dirty look. So I suddenly snapped very loud at the old lady "yeah and did it even occur to you it might have been too noisy and crowded for us to notice? And there are nicer ways to say it goddammit." People were looking at me and my sister was like "Nessa come on, it's okay." This urge is something I can't control. Sometimes I wish I could control it more but I can't. I tried so many times but I just can't.
