I know the internet is not a good place to be naive, but I find being overly cynical is not a good state of mind to be in - for me. I ocassionally override the "maybe scam" siren in my head if the help I provide is a small amount or non financial.

I can afford to give away the cost of a meal at a restaurant or other small equivalent once in a while without it making a material difference to my own finances.

Always be wary of giving away money, but sometimes a little money is the best help that can be provided.
