Has any other had an accident for not making it in time?

4 days ago i peed my pants on my way home after being out shopping. It was close to my house so I don't think anyone found out except for my mom and my friend who I was with. I had drunk 2 cups of tea and tought that I could hold it until we got home but I couldn't and it all came out. I am still very embarred about it but my mother didn't make a big deal about it and my friend later confessed that it had happened to her only a year ago when she was out skiing and couldn't make it to the bathroom. Me and my friend are both 21 years old. Are accidents like these not uncommon among women and girls? Has any other girl had an accident like this? I still feel bad about it.
