Where I come from there's a saying that you cant stay still and you always need to learn something new. So you will become a more valuable member of society, and life will become even more fun.
Once i flipped through one online store quick deals and saw a trimmer for shearing animals at a very attractive price. Immediately I remember about our cat, she is very fluffy, and my girlfriend often complains that the whole apartment is in a cat's fur. Here it is! I realized that if i buy this thing i will do two good things, i will make my girlfriend happy and try something new.
Here, estimate the cat before shearing.
And the cat after the haircut.
P.S The girlfriend is happy, but cat is not so happy
