A woman on the bus dropped her ticket purposely on the floor of the bus. Totally first world problems of mine, I know, but it irked me. If the bus wasn't so busy, I would've asked her if she drops litter on the floor at home and asked if she realises someone has to clean her rubbish up. It probably wouldn't have registered with her though. Other things is people pushing each other to get on the bus, even ensuring they got on before an old lady.
Another much more serious thing is war. The absolute desperation that war causes. My goodness. People killing each other. When does it end?
