My sister has just asked if I want to go out for her next door neighbour's birthday in a few weeks, sounds fine in theory. But, my sister and her partner earn in a week probably more than I get a month. They have no children. Her neighbour is a hotshot Director for a major supermarket, he is engaged, and I know her quite well she is very nice, so no joy there lol. Anyway the evening will be very expensive, the last time we all went out to the same place was for my birthday, so she paid for me (very nice of her), but everyone was happy ordering numerous bottles of Laurent Perrier Rose Champagne, which is delicious but expensive, and I am not sure that I can justify spending so much on 1 night out. I can imagine it being the cost of both DDs swimming lessons for a term, as an example, for 3 or 4 hours out. I really don't think that my sister understands, and I feel like such a loser. Before having children and then ending up a lone parent, I had a good well paid job with good prospects, and now I just feel that I will never have that back, and now I'm crying. And you see if I go out with them I will probably end up coming home and feeling like this again anyway, when they have all been flashing the credit cards around like a few hundred quid is nothing, which it isn't to them!
