This is awful. This lizard is not showing affection. They’re reptiles, not dogs.
Lets break this down
1. “This is awful.”
Ok. This is your thesis statement. This photoset is something you have deemed awful. This is the topic you will expand upon over the rest of this post. Simple start.
2. “This lizard is not showing affection.”
And here we have our first supporting topic. Ok. This is a statement which you have presented as fact, and should now be backed up or explained in some way. Because of course, to make such a statement, you must have good reason to believe this is the case. I look forward to hearing what expertise you have to display on the behavior of lizards.
3. “They’re reptiles, not dogs.”
Ok, this may be a given fact, but it has nothing to do with the rest of your argument. You still have not backed up your point that this lizard is not showing affection, and are instead stating a very blatantly obvious, separate point, immediately after the first one.
In fact, this point is completely irrelevant to your other two statements. If you could somehow bridge the gap between “this isn’t a dog” to “this is awful”, or “This lizard is not showing affection” to “this isn’t a dog”, perhaps there would be some clarity in your argument.
But as it stands, it seems you spitefully assumed something negative about this man and his large lizard pet, and rushed to type up three completely incongruent sentences without any actual evidence supporting any of them.
In conclusion: I want a large lizard.
