As a new user, you did a lot of customizations. Undo them first. Actually, you seem to run the Unity desktop environment, which is not (anymore) the default desktop environment. Log out, then before logging in, click the cog wheel and select Ubuntu desktop to login in to the default desktop.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
