Hi, Why is it that this function: https://github.com/expressjs/session/blob/master/session/session.js#L47-L49 ... doesn't look more like this: ```js Session.prototype.touch = function(){ this.resetMaxAge(); if (typeof this.req.sessionStore.touch === 'function') { this.req.sessionStore.touch(this.id, this); } return this; }; ``` i.e. touch also the session in store?
