The best time to express your love is at 3:00 in the morning.

And, the best way to express your love is by purring.

LOUDLY.

At 3:00 in the morning, the house is very quite so your purrs sound extra loud, even though they already sound like an idling Mac truck to start with.

Make sure you also pat your mom on her face with your paws every three minutes or so, just when you think she's fallen back to sleep.

Alternate that with licks on her eyelashes.

Ignore her when she says, "Piggy! Go to sleep!" and tries to hold you close.

Do not be fooled by her affection. She is just trying to contain your exuberance.

Keep purring and patting and licking her.

She will appreciate being shown just how very much you adore her.

Serious.
