Hey Leo, welcome to the forum buddy! Don't worry at all about "doing things wrong", it's all about learning, that's the fun bit! I personally feel the hardest part for me is the opener, so we are in it together for sure on that one. Just talk to anyone to start off, man, woman or beast. Doesn't matter if they say fuck off, you just need to get their attention. Baby steps! I'm sure people here will have your back and guess what, you just opened the room with your first post. Easy huh?
