Dear, friend.
Thank you for the computer mouse that you have given me, it is very useful for me. Mine has broken and I couldn't use my computer at all when I needed to do school projects and play video games. My brother was annoying me,begging me to get a new mouse or fix it. Thank you once again, Im very thankful .
