So I described the person he sells that call option to?
Yes. And while you have the basic gist of options, there are some nuances that you're missing. Unfortunately I don't have the time to go into them at length, but I'm sure some other more experienced poster here could explain them. I just wanted to make note of it.
In brief -- you can still profit off of call options if the stock doesn't reach the strike price (but moves upward after you purchase the option) as long as you sell to close the option before the option expires. Options expire on the noted expiration date at market close. You don't need to "exercise" a call option to make a profit, but rather can sell to close the option and reap the same amount of profit as if you had exercised the option. You only "lose the lot" below the strike price if you let the option expire worthless.
Generally, I would say avoid short-term options if you are risk averse. They are much more volatile than longer term options.
I'm sure even I got some of that slightly wrong -- after all, I've still got my water wings on myself. ;-)
