Do you think it is necessary to give expensive gifts

It all depends. If you just want to show someone your careness,a small gift is OK,and it'll make recievers not that close to you easier to accept.But, if you think only a expensive gift can match the person you love, go ahead, get him or her the gift,because against love ,all the things that matter ealier become pale.
