Auld saws speaks suith. Old proverbs tell the truth. Auld speugies is ill tae tame. It's difficult to teach an old dog new tricks. If they had more sense they would soon have more money.
Aa things haes an end, an a pudden haes twa.
All things have an end, and a sausage has two Aye tae eild but niver tae wit. Alway growing older but never wiser. Bairns maun creep or thay gang. Those who don't succeed very well at first may do better afterwards. Be taen til the fair.
