<human>: My phone has recently run out of storage and I deleted the Facebook app to save a little space. Because of this, if I decide to use Facebook I have to do it via chrome and I'm not used to it..

A friend of mine (We used to know each other via work, haven't spoken in a few years) very sadly lost a young child recently to illness and had made a post remembering him.

I'm browsing away and I hit the image to scroll down, but something weird happens. So I press again quickly trying to get the page to scroll down. It won't, so I press again panicking that I am going to like the image or something.

It's worse. I tagged my girlfriend in a photo of their child lying in hospital. I wanted the world to swallow me up. It took me a few minutes to untag it again and I'm sure they would of got a notification. I wanted to say sorry, but also just wanted to hide. So I hid. We haven't spoken.

Can you summarize the given text in a few sentences?
<bot>: I tagged my girlfriend in a photo of someone's dead child and then handled it badly by pretending it didn't happen instead of saying sorry.
