HOW DO YOU...??

When you think it’s an abandoned child, and you took them home to adopt them as your own child, but then you realised the extra pair of hand, but you still insisted to raise them as your own child, but then when the child’s parent came with anger and panic to find their missing child, and then you realised what you did wrong, then what you can describe what you did will be like;
“ I accidentally abducted a child”.
