No 1. Get Mrs ao's approval on the rug before buying it... No. 2 Remember that 'approval' does not mean - 'I was thinking about getting one of these...from this place, what do you reckon' No 3. Don't let the children get too comfortable on it, before Mrs ao has seen it. No 4 Let Mrs ao choose the rug next time. No 5 Stick to digging up Lilac shrub/tree roots with a grubbing mattock.
