My DP's narration of the weather - if its not blue cloudless skies, blistering sunshine, and 25C heat beating through the windows, he'll say "It looks cold".
It annoys me on multiple levels.
Firstly, he says it in a way which is half-asking me about the temperature like I'm some kind heat diviner. This'll be at 7am when we've both just got up, I haven't been outside and he's stood right by the backdoor out of which he can very quickly poke his fat head. Why the fuck would I know the temperature?!
Secondly, related to this, his half-asking tactic is a veiled question about what he should wear - does he need a jumper, a jacket, a hat gloves, shorts etc. I don't know because (as above), I haven't been out in it. But I also don't know because I'm not him, I don't experience the world and its temperatures and climates in the same way that he does. Stick your nut out the door, find out the temperature, then decide on your attire.
Thirdly, it suggests that there are only two temperatures - hot or cold. If it doesn't look boiling hot, for DP, it must be cold. Not mild, not temperate, not a little bit chilly, not warm, not warm-ish. Nope, hot or cold. This irritates me. Immensely.
Finally, he's relying purely on visuals but temperature/weather/climate is a multi-sensorial experience. Just because there are a few clouds and the sun's not beating down doesn't mean its not hot. Similarly, a cloudless sky with bright sun can happen in the middle of winter but you wouldn't assume it was 'hot' (well, DP probably would).
