Yeah, Sidd, about your GF will hate you and your friends will not understand you, I can relate to your feeling. All of my family members thinks i'm crazy for collecting "plastic with neon light". My GF think I'm spending my money on a useless things. They are all thinks that I'm childish and stupid for collecting lightsabers. Hahaha.....
But, it's worth it...
