I'm 30, my mother is 60.
Today me and DH had the day off and went into town during which time I did three things that have stopped me dead in my tracks because of how much like me mother they were;
(1) A young man was cycling fast on the pavement. I shouted after him that he was a maniac. There are numerous elements of my mother in this- (a) I felt it was okay to yell at a stranger in public; (b) I used the word 'maniac'; (c) I judged him based on his appearance; (d) I described him on MN as a 'young man'.
(2) I saw a teenage boy dressed what I thought was absurdly. When he was out of earshot I said to my DH 'What did he come as? Is this what the kids wear nowadays?'. There are a number of elements of my mother in this- (a) I noticed what some random child was wearing; (b) I commented on it in public and someone could have known I was referring to him but I didn't care; (c) I referred to anyone under my age as 'the kids'; (d) I had to ask if that was the fashion, I didn't just know.
(3) When we got home, we made a cup of tea and I stood in the window looking at the street whilst I was drinking my tea. I gave DH a running commentary of what tradesmen every house had working there, what it looked like they were doing, speculating on the price, speculating on how much value it would/wouldn't add to their house and commented on how reliable the tradesmen looked. This is my mother through-and-through.
Are you turning into your mother. How? Does it freak you out? Or are you quite happy about it?
I'm quite happy that I might give as little of a shit about everything like my mum but not so happy about turning into a generally annoying, moany grump.
