When clients calls me, and tells me that the website is broken.
client: It won't upload my pictures, says that file size is to big.

me: How big is your picture?

client: How do I check that?

30 min of explaining and a him forgetting to charge the laptop.

Client: It says 32 mb.

Me: Yep that's way to big, won't work for a website.

Client: How do you make them smaller?

Me: Crying.
