I often think about this.
Since I was a child my family have joked that I'm "tight" (because I used to save my £2 a week pocket money up to buy cool toys or clothes I really wanted whereas my sister used to spend it all on sweets and tat from the corner shop the same day she got it and then moan that I had nicer stuff than her). But then it became a "thing", you know how these things do, and they're always making a big deal about it any time they perceive me to be attempting to save money at all. But the fact is, since finishing university, I've never had a particularly well-paying job. So sometimes for example I have saved up money to go to a music festival and then eaten tinned beans and soup all weekend because I could afford the ticket price but not the cost of food from the food stalls. To me that's being careful with limited funds to ensure I can still enjoy myself, but to my family it's being "tight". (I've never been sure if they don't actually realise that if I wasn't as careful with money as I am then I'd end up going hungry and having the leccy cut off eventually... or if they just think that outcome would actually be preferable to the embarrassment of having a daughter who's "tight"...)
Or, I'll buy a lower quality version of a product (say, the £20 version rather than the £200 version), and then I'll be called "tight" - when it's like, if I bought the £200 version then yes, it'll last decades, but I'd then have to choose something else in my life to cut out to be able to afford it: whether it's eating less for the next couple of months, not going out with my friends for a few weeks, not going on a weekend away later on in the year, or not buying something else I might want or need.
Some people can afford to buy the high end stuff and carry on living a comfortable lifestyle, whereas for some of us it's either/or. But it's amazing how blind some people are to other people's financial situations... even if they've been there themselves in the past, they seem to end up forgetting.
