Graffiti...vandalism or art?

I got out with my camera today, which I've not done for...too long! It was really nice to be taking photos again and thinking about what would make a good picture, what angle to take it from, what to focus on etc. While I was there I took the photos below, and wondered what other people's opinions of this where...is graffiti vandalism or art?

My opinion is that as long as it's not anywhere inappropriate (e.g. road signs, on someone's property) then it's art. It's a way someone can express themselves, their creativity and imagination.

Drugs

Drugs are another thing I have very strong opinions about. I hate them. Drugs affect the way a person thinks, the things they say and the way they behave. A person's not themselves when they are under the influence of drugs, that's the main reason why I hate them. They can make people do stupid things and say things they don't mean. I hate seeing people who've had too much to drink. When they can't even walk straight, act clumsy and  the way they can talk to you. Things which wouldn't happen if they could think straight. That's why I very rarely drink anything alcoholic, because I don't want that to be me.

Don't ...

Don't make promises you can't keep.
Don't say something you don't mean.
Don't say something if you're not going to follow it through.
Don't build someone's hopes up only to let them down.
Don't give someone a reason not to believe what you say.
