- Some comments that people say are not very nice. But, you just have to get over it, stay strong, and say something nice back. Also, commenting can help you, with knowing what you did wrong. The other people might say, ´´This brings back memories´´, or ´´You did not spell this word right´´. Some peoples comments give you information you could use. Like the two examples I just used, one is helping, the other is off topic. Because then they will go on talking about something random, and change the topic. Commenting can help you understand if you made a mistake or not, if you use it correctly.
