There are two compound sentences: "I didn’t plan on spending my weekend in a basement watching someone else play video games, yet here I am" and "Eat all your vegetables or you’ll get no ice cream tonight".
A compound sentence is a sentence made up of two or more independent clauses that are joined with a conjunction. At the same time, in contrast to dependent clauses, independent clauses, which contain a subject and a verb, can stand by themselves as complete sentences. The first compound sentence is made up of two independent clauses ("I didn’t plan on spending my weekend in a basement watching someone else play video games" and "here I am"). They have been joined with the coordinating conjunction "yet". Moreover, the second compound sentence is also made up of two independent clauses ("Eat all your vegetables" and "you’ll get no ice cream tonight"). They have been joined with the conjunction "or".
