Luke: Lucas would be so nervous and he would probably keep on asking you if he should take his lip ring out and “What if they don’t like me babe?” and start freaking out about every little thing. You would have to reassure him that they would love him and give him a quick kiss on the cheek before knocking on the door and he would address your father as “Sir” and give him a hand shake as he does that nervous thing with his feet aw aw.
Michael: I feel like Michael would also be nervous because he has bright red hair for gods sakes as well as an eyebrow and ear piercings. When meeting your parents he would have a firm grip around your waist half because he wants to show that he loves you and half because hes nervous and doesn’t know what to do with himself poor baby. After meeting your parents he would nag you by asking if your parents liked him and you have to reassure him that they do.
Calum: Calum knows he is charming as hell so he would most likely turn up with flowers for your mum and compliment her on her hair or outfit then wink at you that cheeky shit. Then when meeting your father they would easily get along and just smooth talk about something that they both have an interest in. If you just had lunch and dinner he would probably ask your mum if she needed help with packing up or doing the dishes. Then when everyone is saying goodbye your parents would quickly pull you in and say “I like this boy” because lets be honest everyone loves Calum.
Ashton: Ashton would be a lot like Calum in this situation by starting off with a compliment to your mother then greeting your father with a firm handshake and a smile. Through out lunch or dinner he would make sure to tell your parents how much he loves you and how much you mean to him and that he will take good care of you and how you make him so happy and he would have this really huge smile and probably laugh at every one of your dad’s jokes with like seven different giggles oh my god.
