In 4000 years...

Tonight at dinner Will says to be "In 4000 years mom, will you let me go shopping all by myself?"  He then confidently says "I'll probably be like 16 by then"  Sure I say and what will you buy?  'Well maybe that's just 1000 years away.  I'd buy legos and toys, and stuff like that."  Cool.  If you promise to keep buying legos when you are 16 years I will be overjoyed that your life is still so simple and wholesome.
