The memories you share with people last a lifetime but the memories you share with yourself last forever till you die. You die with those memories whether you choose to share them and make other people laugh or you keep to yourself for good reasons or so you think.
We collect and make them whether they are good or not. You hold them tight, some will make you cry and others will make you smile.
Memories can be anything from sharing secrets with that special someone to holding hands with someone you love.
