Two pub evenings with different sets of friends; two discussions about house prices; two utterly different moods.
Last Monday night, there were glum faces all around the table; on Thursday, gleeful ones. Bizarrely, the cause of the joy and pain was the very same: last month's figures for the housing market.
According to Nationwide building society, the market cooled swiftly in April. Blink and you'd have missed an average price rise of 0.1 per cent on March (and annual inflation edging down to 4.5 per cent).
For one couple on Monday night, this stagnant market was proving an expensive nightmare. They were mortgaged to the hilt, they wailed, and the price of their two-bedroom flat - bought for £205,000 as an investment early last year - hadn't budged. Their hope of remortgaging within a year with the new-found equity in their property looked wildly over-optimistic.
Fast forward three nights to a different pub and a different set of financial data. According to the Halifax, Britain's biggest mortgage lender, April had been a stonking month for homeowners. House prices were up 2 per cent from March - the highest monthly rise for two years, and 20 times the estimate at Nationwide. Annual inflation was a nifty 8 per cent, it calculated.
That evening, one of my friends was feeling quite smug. He was sitting pretty on a semi, and his plans to move by Christmas should, he reckoned, net him a cool £15,000 in equity in just 18 months.
From zero to hero in 72 hours, the UK housing market continues to bamboozle many people, who ask how the same month can produce such contrasting sets of statistics.
The answer comes down to the different ways in which the Nationwide and Halifax figures are calculated. These include the precise weeks measured (Nationwide includes the last 10 days of March in its April figure); the type of "average" house looked at; and the size of the sample (the Halifax says its pool is more than five times that of its rival).
Housing market figures can dramatically affect buying and selling decisions, so you might think it important to know which set is right.
In fact, it transpires, neither is, and that the resulting anguish is our fault.
We really shouldn't be getting worked up over these short-term figures, lenders warn. It's the picture over many years that matters. In this case, both Nationwide and the Halifax show broadly similar, slow upward trends - with little sign of an imminent crash, despite countless predictions from so-called experts.
This should be reassuring news for most homebuyers and sellers, but it is alarming to see the eagerness with which the monthly figures are still seized on by many.
On both my pub nights, one common strand emerged in the discussion of house prices: my friends looked on their properties as short-term investments, at the expense of all else.
Pensions? Much less important. Savings? Only if there was any money left at the end of the month. Investing in shares? Hmm, just a little in most cases.
It's no secret we're a nation of home lovers, but until we calm our anxiety over every property price move, we're in danger of not seeing the wood for the trees.
A home is just one of many investments people make in their lives, although to be fair, it is usually the most expensive. But if we could spread ur addiction to the housing market to other parts of our personal finances, we'd be in a much better state of financial health.
Now, that's a nation of junkies we could do with.Reuse content
