Your not alone Hubby I tend to do it too sometimes, usually when shopping and I'm at the checkout, I'll say something like... 'I'm still getting used to doing the shopping myself' and when they look at you in response I'll add 'My wife passed away in April'.
Maybe subconsciously we're seeking a little sympathy perhaps? I've said it about 3 times over the last couple months, something I need to stop doing. Though in reality it was intended to explain why this old fool is fumbling too much as they can see I'm not that proficient at this shopping lark quite yet...lol...I don't have a lot of use in my left hand, so that doesn't help either when transferring items from the trolley onto their conveyor belt thingy so a bit slow, and often dropping things...lol
I dropped a 2ltr bottle of diet coke a couple weeks ago, which decided to explode when it hit the floor, most embarrassing...lol..but the staff were very good though.
