Should I take my son a cooler T-shirt to college?

[Ketley67]

DS 17 has phoned from college asking if I can take him a different t shirt as he’s too hot (it’s made out of thick fabric). I said no.

Im off work today but I can’t be bothered to drive across town in this heat with no air con when I’ll be going to pick him up in 2 hours. It would take me all of about 10mins.

Am I a meany or should he just suck it up?

If it would take me 10 mins and I wasn't super busy I probably would.
If it would be more like half an hour by the time I'd parked and handed it over or I was in the middle of doing things, then I wouldn't
