Hmmm... could it be that she got a bit lazy because she hasn't
done it in a long time? I think my mom kinda like that.. She used
to bake a lot of cakes and nonya kuehs but she doesn't do so
anymore. Her pandan chiffon cakes were better than Bengawan Solo's,
but she can't replicate that anymore. 
Or could also be because she's getting on in years and her bones
are feeling too cranky so she'd rather not move.
