Good Character

Q: I would like to know if this is correct.

There is a person who lent me his computer. I connected to my internet account from his computer and by closing the session I forgot to disconnect my account from his computer. Is it allowed for the owner of the computer to view my files which are stored on Google Drive? Does this person have the right to go to consult my Google Drive account without my knowledge and without having my permission or authorization?

Q: What are the rulings of Shariah on social activities and chatting after Esha prayer. Nowadays, we see people start visiting relatives after Esha or just sit at home and chat with the family as according to them this is the only free time they have?

How about the same with one’s spouse? Is there any clear guideline on it in oue beloved Shariah and what is the sunnah?

Q: If someone sneezes in a dars whilst the speaker is talking and says Alhamdulillah then should one reply? If one didn’t then can one reply later?

Q: Can you please let me know the adab and sunnah of letters? For example, letter writing and receiving letters.

Q: Could you please give any advice how to stop lying?

Q: I would like to know if it is permissible to expose sins if you need help and advice and you are not proud of the sin you're exposing.

Q: If you get thoughts, urges or daydream about showing off your worship to other people so they will praise you but you don't act on the thoughts or urges, would you be still a sinful? Basically they are just thoughts, desires and urges of showing off in your heart but you don't physically show off.

If you get thoughts or daydream or images in your mind of shirk and kufr but never act on them physically, they are just in your mind, would you come out of Islam or become a disbeliever? 

Q: A certain Darul Uloom has said that it is permissible to make gheebat of an oppressor? Is this true?

Q: If one has made gheebat or slandered someone without their knowledge, is it necessary to tell them about it and seek their forgiveness or can one just ask forgiveness from Allah?

Q: I wanted to ask which sin is lesser of the two evils, exposing one's sin or lying? I am asking because if someone asks if you have comitted a sin, is it permissible to lie and say you haven't? Would that be better than exposing your sin? In a situation where you cannot avoid the question?
