In this case,it has many many different answers.It depend by the gentlement who take the girl home?
These are the 2 examples.1.The gentlement maybe love the girls inside his heart already,but he isn't ready yet to put the words together and express his feeling to her,that's why he want to take it longer to walk with him so he can have enough time to think and how to express his love to her? 2.If it's their first date,he sure want to know more about her,it can be the reason why too.If she asking me why,I would answer with my gentlement manner.Tonight is a very beautiful evening with the nice weather.I am very enjoy this evering and conversation with you.
If any ladies out there is not happy why he take it longer to walk with her to her home.I am for sure she would tell him right away when the time she arive her,it won't be question and answer at all.Relax and take it from there.
