My own oak

I picked about 25 acorns at my darlings boy's grave last autumn. And poked them in the soil at home on the balcony. Now I have a little oak.. And it looks prosperous. 
The payoff is very low. A measly oak of 25 acorns. But if this one manages, that is enough. I get my very own oak tree. Considering how slowly they grow, I do not have to worry about it getting too big for my balcony in my remaining lifetime
