Be yourself Westie. If you like who you are who are others to change you. You helped out someone in need and you got burnt, but dont let that put you off helping. There are always going to be people who will screw you over at the first chance you get but their are also some genuine people out there who would appriciate any help that you give them.
If being like Oscar the Grouch is your thing go for it
We all Love you anyway man
