My sister is the absolute worst - she only rings me 2 or 3 times a year and she only rings when she's got 2 minutes credit on her phone. And the first thing she tells me is she's only got 2 minutes credit on her phone. Fucking annoy me the lot of em.
I think it depends - DS1 has unlimited texts on his phone but calls are expensive so I have told him to text me and I'll ring him back. DBF knows that with the DCs it's not always convenient to talk so she'll text me and I call her when they are in bed or I have 10 30 minutes to talk. DM on the otherhand never has must credit and knows I get free calls so often texts and I call her back.
Anyone else who I don't have a kind of prior arrangement with then i don't think you ABU as it would make me cross too!
My Mum does this. She still doesn't get the notion of inclusive minutes. Its actually probably costing her more in texts asking people to call her than if she actually phoned herself. Although in her defence, I think part of it is she knows I'm always mentile busy and thinks its more polite to ask me to call when its convenient for me rather than disturb me with an ill-timed call.
I always ask people to call me! I get free minutes so it's not that, just I guess it means they can chat properly at a time thats convenient to them instead of me calling at a busy moment, I totally never thought it would presumed I was too cheap to pay for a call, mortified.....
