Just Something To Keep In Mind - Quoting @Niki7a
"Don't just ask them if you can help, instead look at what needs done and say 'I can help with this (specific problem) if you'd like a hand'. It's a lot easier to accept help from someone if they are specific than it is when you ask them if they need help, because that is too open ended."
"If you offer specific help, like 'I can help you carry that', or I 'I can hold the door for you' or ' I can untangle those cords with you'. All those thing are a lot easier for someone to agree to, once you have helped you can then make friendships..."
