Peace and Blessings to you All I know, invisibly chatting is easy and you may feel relax and no fear. But, Almighty Allah sees even what we think. You can write everything what you think, however, You must fulfill rule which Islamic rules. My dears, please be careful and think deeply before writing. Sometimes we are witnessing two unlawful teenagers talking about bad things and simultaneously enjoying what they are talking. Allah knows best. I repent to Allah if I have mistaken.
