As the song says love sweet love but I think we need more than this. I think everyone should start being nice to who ever you meet on your daily routine. For example if you are coming up to a door at the same time as someone else, open the door for them instead of you going in first. You could also hold the door open for them after you go in. I don’t think people are friendly to each other anymore. Don’t if make you feel good when you help others. That doesn’t mean you have to give them everything you have just lend a helping hand once in a while.
