after writing this ive seen how long it is, so sorry, there is a point to it, promise!
no your are not being unreasonable at all! my mum has retired recently from the same career path as me, and as i am now on mat leave (due this time next month) she keeps coming round with no notice.
in the past week:
she has phoned saying 'can i come round?' answer, 'yes, later, still in pj's' (10am). she then said, ok, il come round at the weekend instead'.HUH?
the next day she rings again, 'are you up?'
'yes'
'good, can you open the door please?' (WHAT THE HELL sprang to mind at that point). after 10 days straight at work, it was my OH's day off, so we were happily watching tv (in pj's - 9am), with intentions of doing the washing up, washing etc later that day. we felt we had no choice but to let her in, but needless to say we were getting annoyed at this point.
the following day (!) she knocks on the door again with no notice. id had a bad night, so was 'asleep' in bed (ignoring the door). my OH is on the pc doing his work, she proceeds to knock on the living room window at him and points at the door. he had no choice but to answer the door, for fear of appearing rude. luckily he had the opportunity to say i didnt want to be disturbed, so he stopped her at the door before she could come in demanding a cup of tea - i love my OH!
finally, today - i promise there is a point to my saga of a story - she knocks on the door again with no notice, by phone or text. I snapped, finally.
i very calmly told my OH to hide in kitchen so she cant see him from the door, and to stay quiet. i then took my t-shirt off - bra underneath! - and quickly open the front door wide open (il add at this point that there are no houses opposite us, and we live in a very quiet cul-de-sac) to reveal my rather large 8 month belly complete with stretch marks, and rather p'd off expression.
the look of shock and confusion on her face was priceless - 'why have you answered the door like that?!'
'because we were about to have sex Mum, we were halfway through getting undressed and you knocked on the door. as we were in a bit of a hurry to get upstairs ive answered it dressed like this. perhaps now you'll ring or text first to ask if it is convenient to come round?'
she left rather quickly, and obviously told dad when he got home from work. got a call from him asking what the hell had happened, with mum expecting him to have a go at me. he didnt, he completely sided with me, i think she's got my point.
moral of the story, dont just ring to say you're coming round, ask me if it is convenient! otherwise operation embarass parents will be started.....
judge all you like if you want, my method worked for me!
