If someone is proud of their house, they probably enjoy having guests. They might want to share their home with others, not to boast, but just to share. If they are also good at cooking, they likely enjoy having someone to cook for, so inviting people gives them a reason to prepare a meal.
如果有人为自己的房子感到自豪,他们可能喜欢有客人。他们可能想要与他人分享自己的家,不是为了炫耀,而只是为了分享。如果他们也擅长烹饪,那么他们可能喜欢有人可以煮饭给,所以邀请别人来是他们准备一顿饭的原因。
