Regardless of what kind of relationship You're into with someone,either friendship,or romantic, courtesy is definitely a vital ingredient. We tend to take people We're intimate with forgranted,yet we expect them to stay committed and not feel bad about it... Courtesy is going into extinction in our society like imagine a guy pushing a gal off all in the name of rush hour,better still a imagine a lady not knocking before entering a guy's room let alone waiting for a 'COME IN' before entering...ewh!!! Using words like Please,just one mins,excuse me,hold on a sec Pls...etc help earn respect. Never put someone on hold just to talk to another without excusing yourself from the first party. Never open the door to a room without knocking and waiting for a 'come in' before entering,knock at the toilet's and bathroom's door to confirm if anyone is inside,don't just barge into rooms. Learn to say Pls when asking for people's favour,sorry to say this,I've discovered that some ladies now a days are very poor when it comes to saying Pls when asking for favour especially when It's from a guy. It's not Good... Here are few examples of Simple,but important courtesy.
>Knock and wait for a 'come in' before entering any room.
>When you yarn,cover your mouth.
>Say Pls when asking for people's favour.
>When you see people for the first time in the day,greet first before starting any discussion.
>Excuse yourself from a previous discussion before jumping into another. Don't put someone on hold to discuss with another.
>Say thank you for every favour shown,either small or big.
>Switch off your phone in the church or put it on vibration if you know you can resist the temptation of attending to calls during service,since it is not good to put someone on hold to attend to another and picking calls during service simply means putting God on hold to talk to man.
>When complimented,say 'thank you'... Etc. Try it out and you'll be amazed with the outcome. Pls Let's orientate our society about courtesy and I hope this post have set another reminder.... With care,Princephelar

Good write up

Thanks for the reminder, not in relationship alone but in every facet of life

Coutersy exists mostly in formal relationships unfortunately when you start sleeping with one another, the relationship becomes anything but formal

Op thanks,courtesy is very important both in formal and informal relationship.

Thanks Guys for the encouragement, I am glad you like it.
