Fucked by my neighbor

Today is a quiet day and I'm bored, so I invite my neighbor to me. I ring his bell and he was pleased to be invited by me. We go to me and I offer him something , I accidentally spill wine on the pants of my neighbor .... without what now? I hope he is not mad at me now! But he tells me that he has an idea how to make it up to me and would like to offer me a suggestion. What that can be ?
