ELI5: Why is the paint I put on the thing I'm painting still wet, but the paint I got on my shirt already dry?

Your shirt is made of fabric, which absorbs moisture pretty well - better than your average wall or whatever.  So when the paint hits your shirt, your shirt fairly quickly absorbs the liquid content, which is small enough that it's almost unnoticeable.  The pigments and solids of the paint stay on the outside of the fabric, feeling dry much more quickly than if you were painting on a hard surface.
