For slightly over year I have been unemployed. During the day I get bored and just walk around like a ghost in my local town centre (I live in quite a small town) and sometimes 'I' myself find it funny that I aimlessly walk around.
Today I walked past this group of youths at my local towns park and I heard them saying behind my back "Have you seen that guy before he just walks around town all day" I then turned around to look at them and they burst out laughing at me and I felt really embarresed.
Do you think I deserved to be laughed at for my actions?

British youths living in a small town have nothing to do but insult passersby? They are, perhaps, the most useless of humans in that region of Earth. I would advise fastforwarding your imagination about 10 years, and seeing them as the stunted slothful slugs they will very likely become. You, on the other hand, are getting daily exercise and surveying of your community.
So, no. You don't deserve to be laughed at for your actions or any other reason. They are bullies. Shun them.
