A lazy day

Good day today. Slept late, exercised, avoided stress.

Not looking for much excitment this weekend, just hoping the tornados hold off long enuff for me to get the grass cut.

Don't understand what's going on with my tomato plant (yes, just one) Top leaves are green and waxy, lower leaves are yellowing. Any thoughts? Too much water, too little, issues with the cold, not enuff food?

Help!
