Covalent Bond Types are like Eating in a Restaurant

I need all the help I can get in understanding chemistry and the analogies were very helpful in figuring out how covalent bonds work. If you are not used thinking in terms of chemical bonds, molecules, atoms and all the rest then it makes it almost impossible to visualize and it seems so abstract. Using examples that we can relate to from our own experience where we can actually comprehend these actions is useful in understanding the nature and behavior of it all.
