My sister is going to get married on August with a men I can't stand. He's totally ok with child labour and we had a disagreement after he told me that wasn't fair "Mein Kampf" was canceled. And since then I just can't see my sister marring him. We have a lot of sister and brother and I'm the only one who said I'll go to her mariage but now I just want to cancel my flight. AITAH ?
