Phew! When I read the title I thought bloody hell, that's my husband!
Am glad to hear the boys are the wrong age and it's a laptop!
ok - you are probably going to get a hard time from a lot of people, but I won't join them.
MN can be addictive. I know I can get so sucked in that I log on first thing!
If someone was to check my threads, they'd see me on at all times of the day.
There have been times I have been on all day when I get that bad I try to log off for a few days. My husband has previously voiced concerns similar to you.
However, it is possible to look as though you are on all day. Take a typical example of a day.
Get up, grab a coffee and post on a thread
get the kids up, get their breakfast, while they're eating it, post on a thread
get the kids to school, come home, grab a coffee and post on a thread.
go put some washing on, wash the pots, mop the floor, come back and post on a thread
clean upstairs, come back, have half an hour posting on threads
hoover the living room and polish, come back and post on a thread
go fetch the kids, while they're watching tv, post on a thread
make tea, kids have theirs at the table, you eat yours in front of computer
homework, chatter, quality time..then sit down with a cuppa and post on a thread
get the kids bathed and to bed then settle down with a glass of wine and MN
5 minutes here, 5 minutes there, nipping on and off... it can seem like you have sat in front of the computer all day.
By the time I have posted this, I am sure you will have had the flaming of your life! But I don't think it is automatically unreasonable to be concerned if someone seems to be becoming consumed by something - especially if you fear it may result in them having altered priorities that ultimately damage the family.
